Cancer is the abnormal, uncontrolled growth of cells in a particular body part. With continued growth, pieces of this tissue travel through the blood to different body parts and continue to grow in the new area. This is known as metastases. Breast cancer is one of the most common forms of cancer and affects about 1 in 8 women in the USA. Read on to know more details of breast cancer   breast anatomy, causes, symptoms, risk factors, detection, prevention, and of course treatment.

Anatomy: The main function of the breast is lactation through its milk-producing tissue that are connected to the nipple by narrow ducts. In addition, there is surrounding connective tissue, fibrous material, fat, nerves, blood vessels and lymphatic channels which complete the structure. This is essential to know as most breast cancers develop as small calcifications (hardened particles) in the ducts or as small lumps in the breast tissue which then continues to grow into cancer. The spread can happen through lymphatic or blood flow to other organs.

Warning signs/symptoms: The following are some symptoms that need to be watched out for if you have a predisposition to breast cancer.

    A lump in either of the breasts or armpits
    Change in size, shape, or contour of either breast
    Redness of your breast or nipple
    Discharge of clear or bloody fluid
    Thickening of breast tissue or skin that lasts through a period
    Altered look or feel of the skin on the breast or the nipple (dimpled, inflamed, scaly, or puckered)
    One area on the breast that looks very different from the other areas
    Hardened area under the breast skin

Either one or a combination of these should be an indication to get a detailed checkup done. Early diagnosis results in controlling the disease with minimal treatment and reduced complications.

Causes and risk factors: The exact cause for breast cancer is yet to be pinned down. However, risk factors are clearly identified, and women with risk factors need to watch out for warning signs.

    Family history: Of all the risk factors, the family history is the most important. Breast cancer runs in families, and if there is a first-degree relative with the breast cancer, the chances of developing it are almost double. Two genes BRCA1 and BRCA2 are the carriers of the disease, and this testing can be done in women to identify if they are at risk.
    Family history of other cancers: Even if there is no breast cancer, if there are other cancers that run in the family, watch out.
    Age: Women over 50 are at higher risk of developing breast cancer.
    Race: Caucasian and Jewish women are at higher risk of breast cancer than African-American women.
    Hormones: Greater exposure to the female hormone estrogen increases the chances of developing breast cancer. Women who use birth control pills for contraception and hormone replacement after menopause are at a higher risk of developing breast cancer.
    Gynecologic milestones: Women who have abnormal menstrual milestones need to watch out. These include those who attain menarche before 12 years of age, get pregnant after 30, attain menopause after 55, and have menstrual cycles shorter than 26 days or longer than 29 days.
    Obesity and alcohol abuse are also likely to increase a woman s chances of developing breast cancer.

Stages: Starting from stage 0, higher stages indicate advanced disease.

    Stage 0: The growth which has begun in the milk-producing tissue or the ducts has remained there (in situ) and not spread to any other area, including the rest of the breast.
    Stage I: The tissue slowly becomes invasive and has begun to affect the surrounding healthy tissue. It could have spread to the fatty breast tissue and some breast tissue may be found in the nearby lymph nodes.
    Stage II: The cancer at this stage grows considerably or spreads to other parts. There are chances that cancer may grow and also spread.
    Stage III: It may have spread to the bones or other organs but small amounts are present in up to 9 to 10 of the lymph nodes in the armpits and collar bones which makes it is difficult to fight.
    Stage IV: The cancer is widespread to far-flung areas like the liver, lungs, bones, and even the brain.

Screening: This is one of the most effective ways to identify the disease in its early stages. This will help in controlling cancer from spreading with minimal treatment.

    Self-examination: A thorough self-examination to look for changes in terms of shape, size, colour, contour, and firmness should be learned by all women. Watch for any discharge, sores, rashes, or swelling in the breasts, surrounding skin, and nipple. Examine them while standing and when lying down.
    In most women, annual screening mammograms are advised after the age of 40. However, in women who have a strong family history or genetic makeup, it is advisable to have screening mammograms starting at age 20 every 3 years and then annually from the age of 40.
    Women in high-risk categories should have screening mammograms every year and typically start at an earlier age.
    Ultrasound screening can also be given in addition to mammograms.
    Breast MRI is another way to screen for breast cancer if the risk is greater.

Breast Cancer Prevention: Now that there is so much awareness about causes and risk factors, there are definitely ways to prevent or delay the onset of the disease.

    Exercise and a healthy diet with reduced amount of alcohol are definitely effective in minimising the chances of developing cancer.
    Tamoxifen is used in women who are at high risk for breast cancer.
    Evista (raloxifene) which is used to treat osteoporosis after menopause. It is also widely used in preventing breast cancer.
    In high-risk women, breasts are surgically removed to prevent the development of cancer (preventive mastectomy).

Treatment: As with all cancers, treatment would depend on the stage at which it is identified and include a combination of chemotherapy, radiation, and surgery. As noted earlier, if you are at risk, look out for warning signs as early diagnosis is the key to maximum recovery.

Breast Cancer - Know More to Say 'No' More!

Brain metastases from systemic cancer are the most common type of intracranial neoplasm in adults, being almost 10 times more common than primary malignant brain tumors, which cause a significant burden on the management of patients with advanced cancer (1). The lungs represent one of the most frequent sources of metastases to the brain, with a probability of (36 64%) (3). Symptoms suffered by the patients include headaches, epilepsy, focal weakness, numbness or changes in mental status. The prognosis of patients with brain metastases is not optimistic and the median survival time is  1 2 months if left untreated. The 1-year survival rate has been recorded as 10.4% (4,5). The treatment of metastatic brain tumors is complex; not only due to being able to provide local control and improve neurological function, but also due to factors such as age, performance and systemic disease status and the size, volume, location and number of metastases at presentation

CyberKnife is a robotic radiosurgery system with a linear particle accelerator (linac), which is coupled with real-time imaging to track and compensate for the patient s or target s motion. As a relatively non-invasive treatment modality, CyberKnife demonstrates certain benefits, including a more accurate target localization and improved dose delivery for the management of metastatic brain tumors that allows higher biologically effective dose delivery without increased incidence of toxicity.

In the present case, the results for the treatment of multiple brain metastases after CyberKnife surgery with a 7 8 Gy marginal dose was promising. CyberKnife for metastatic brain tumors is an effective and safe method for reducing the marginal dose prescribed for multiple brain metastases and for minimizing the radiation-related neurotoxicities. In conclusion, CyberKnife, a focused, highly-targeted radiosurgery and fractionated radiotherapy is particularly useful for multiple brain metastases. CyberKnife provides the advantage of the management of local recurrence and a tolerable complication rate. Although the treatment of brain metastases has been performed with CyberKnife, the clinical significance and optimal dose fractionation scheme require further investigation.

CyberKnife Therapy Of 24 Multiple Brain Metastases From Lung Cancer!

The sound of the word cancer can be really traumatic and the fact the one may most of the time be unaware of this condition can be hard to handle. The same is the situation in the case of lung cancer as it does not produce any remarkable signs and symptoms in its early stages. However, there are ways in which you can be aware of this life-threatening ailment. Here are some tell-tale signs of an early stage of lung cancer:

A stubborn cough:
Beware when a cough is lingering on for long with no sign of relief. When a cough is related to cold and respiratory infection, it will subside within a week or so. But in case the cough is persistent, it can be a symptom of lung cancer. You should never dismiss a stubborn cough regardless of whether it is dry or producing mucus. You should talk to a doctor right away as he can check the lungs and may order for other tests to determine whether you have cancer.

Breathing problems:
Becoming easily winded or shortness of breath is considered the most prominent symptoms of lung cancers. This may occur when cancer blocks or inhibit the airway or when the fluid from the tumor starts building up in the chest. If you find that it is becoming difficult for you to breathe in doing tasks that you found easy before, you should not ignore it.



Wheezing:
When the airways become inflamed, blocked or constricted, then the lungs would produce a wheezing and whistling sound while breathing. It can be associated with a host of other causes that are easily treatable but could also be due to lung cancer.

Headache:
Even though headaches are considered one of the most common health problems, if there is a persistent headache, then it could be a sign that lung cancer has spread to the brain. It is important to understand that all headaches are not associated with the brain metastases. There are times when the lung cancer creates pressure on the superior vena cava which is in charge of supplying blood to the upper part of the brain. This pressure can also lead to headaches.

Pain in the bone:
If the lung cancer has spread to the other parts of the body, then it may produce mild pain in the back and other parts of the body. It tends to become worse during the night when you are resting on your back. But it can be difficult for a commoner to differentiate between muscle and bone pain. In case you are suffering from bone pain, you will see that it is becoming worse with movement. Moreover, lung cancer is also associated with pain in the shoulder, neck, and arm even though it is very rare. You should be very attentive to the pain and aches in the body and consult with an expert at the earliest.

You can easily combat lung cancer if diagnosed and treatment is started in its early stages. In case you have a concern or query you can always consult an expert & get answers to your questions!

Five Signs That You Might Be Suffering From Early Stage Lung Cancer!

Let s start with some mind-boggling statistics: in India, over 2.5 million patients are diagnosed with cancer. Moreover, it is estimated that around 700,000 new patients are found to have cancer, each year, and around 550,000 annual deaths are related to cancer.

While these perturbing numbers might unnerve you, there is, however, a case for cautious optimism. While there are certain causes of cancer like genetics and environment which are beyond your realms of control; there are certain causes which can be controlled by you. Research shows that nearly 70% of cancer causes are in your hands   including your own diet.

Your daily nutritional intake is vital for two reasons:

There are definite cancer-preventing nutrients and food items;
Conversely, there are certain types of nutrients and food items which cause cancer.
While research typically points to links between food items and cancer than well-established cause-effect relationships, it is found that certain dietary items have a greater influence. Here are some general guidelines to guide you better:

Avoid processed and red meat: Processed and red meat are generally considered as any meat which has been artificially modified for taste or purposes of preservation. It must be noted that during this process of preservation there are certain chemicals mixed with it which makes it carcinogenic in nature. Though the WHO (World health organization) hasn t recommended any specific amount for consumption, it has categorized processed and red meats as a Group 1   carcinogen.
Consume more fruits and vegetables: Plant foods including fruits and vegetables contain essential micronutrients like flavonoids and carotenoids which researchers  state are powerful antioxidants. Antioxidants help prevent the destruction of cells as they diminish free radicals. It is recommended to regularly consume fruits and vegetables like berries, broccoli, leafy greens, apples, papaya, among others.
Reduce your alcohol and smoking habit: Along with processed and red meats, alcohol is designated as a Group 1   carcinogen by the WHO. Cancer research has repeatedly linked consumption of alcohol to higher chances of cancer, irrespective of the alcohol type. A number of cancers including pharynx, liver, and breast are directly connected to alcohol.
Furthermore, it is suggested that an individual must limit to no more than a drink on any given day.

In conclusion, it must be stated that our diets play an indispensable role in the prevention of cancer. The consumption of healthy food items will only bolster our physical well-being along with the reduction of cancer occurrence.

How Your Diet Can Potentially Prevent Cancer?

Cancer like most other diseases has the best rates of recovery with early detection and intervention. As there are no regular health screenings for blood cancer, only the awareness about the early warning signs can save your life. November is designated as the Lung Cancer Awareness Month, to ensure every individual is equipped to fight against lung cancer right from the start. Here are 4 vital facts you must know to win your fight against blood cancer.
Lung cancer is also known as pulmonary carcinoma or cancer of the lung. It occurs when DNA mutations develop in the cells/ tissues of the lungs leading up to uncontrolled growth in the tissues of the lung. By far, it is known to be the most common cancer in Asia.

1. Type: lung cancers can present as one of the following types: 

Non-Small Cell Lung Cancer (NSCLC): Most common type of lung cancer and constitutes nearly 85% of all lung cancers. The sub-types of NSCLC are as follows:
Large cell carcinoma
Squamous cell carcinoma (SqCC) (Epidermoid)
Adenocarcinoma   accounts for majority of the NSCLC.
Small Cell Lung Cancer (SCLC): It is also known as oat meal cancer and tends to spread (metastasize) quickly. This constitutes about 15% of the lung cancers.
Mesothelioma: It is a rare cancer that develops in the mesothelial cells of the pleural or peritoneal surfaces. It usually arises in the pleural membrane lining the lungs, known as pleural mesothelioma. One that arises from the peritoneum is called the peritoneal mesothelioma and the one that arises from the pericardium is known as pericardial mesothelioma. Lastly, it can also arise from the tunica vaginalis known as testicular mesothelioma. People working with or prior exposure to asbestos are mostly at risk of developing mesothelioma. The latency period between time of exposure and development of mesothelioma can be somewhere between 20 to 40 years. Maximum of the patients who develop mesothelioma are men.
2. Gender: It affects the male populace predominantly. It is more common in men than in women and in those of lower economic status. However, the incidence of lung cancer, in women too, is on the rise of late.

3. Etiology: Cigarette/ Tobacco smoking remains the most important cause of lung cancer accounting for 85   90% of the cases. Incidence/ risk is proportionate to the number of cigarettes smoked irrespective of the age. Also, environmental toxins including smoke from burning black tar, exhaust gases from automobiles etc. too contribute actively to various lung diseases including cancer. People working in asbestos manufacturing factories who are exposed to asbestos dust are also likely to get lung cancer. Tuberculosis too is an additive risk factor. Again, people who have received ionizing radiation especially to treat Hodgkin Lymphoma or other malignancies also run the risk of developing lung cancer. Above-mentioned causes apart, genetic factors may also play a role.

4. Features: Lung cancer clinically presents in the following ways mainly. Signs & symptoms of malignant mesothelioma are as enumerated below

Difficult/ labored breathing (Dyspnea)
Chest pain
Palpable chest wall mass
Discordant chest wall expansion
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Night sweats
Signs & symptoms of non-small cell lung cancer (NSCLC) are as enumerated below. Majority of patients are symptomatic at diagnosis

Chronic cough
Difficult/ labored breathing (Dyspnea)
Chest pain
Blood stained sputum (Hemoptysis)
Hoarseness
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Weakness
Bone pain
Pleural or pericardial effusion
Superior vena cava syndrome
Brachial plexopathy
Neurologic pain
Hypercalcemia of malignancy
Signs & symptoms of small cell lung cancer (SCLC) are as enumerated below

Symptoms as per the points 8   18 depicted above for NSCLC are applicable for SCLC as well. Additionally, patients suffering from SCLC may have:

Fever associated with chest infections like bronchitis/ pneumonia that refuse to go away or keep coming back
Horner syndrome
Paraneoplastic syndromes including encephalitis/ sub-acute sensory neuropathy, hyponatremia, acromegaly, cancer associated retinopathy, ectopic corticotropic syndrome etc all.
5. Screening: is generally recommended for asymptomatic/ symptomatic populations as surveillance for high-risk individuals   who are either current or former smokers (quit smoking within the last 15 years) have at least a 30 pack-year smoking history and those who do not have any prior history of lung cancer. The goal of screening, as usual, is to be able to detect & diagnose lung cancer at an early stage which is potentially curable. It is mostly radiologic with a low dose helical computed tomography (CT) scan being more effective in detecting early-stage lung cancer than a chest radiograph can.

6. Diagnosis: Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for an accurate diagnosis. Following are the diagnostics employed mainly:

Blood: Hb may be low, TLC, ESR and polymorphs increased. Adenocarcinomas are likely to express thyroid transcription factor 1 (TTF-1) or carcinoembryonic antigen (CEA). On the other hand, mesotheliomas are likely to express Wilms Tumor -1 (WT-1) protein and Calretinin.
Imaging: Thoracoscopy, Bronchoscopy, X-Ray, CT Scan etc all. Positron Emission Tomography (PET) / CT scan and Magnetic Resonance Imaging (MRI) scan help detect metastasis if any.
Biopsy: It clinches the histologic diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, chemotherapy and radiotherapy as contextually appropriate. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as would be feasible contextually.

8. Prognosis: Preventive measures, earlier diagnosis and right early treatment are key for effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for early-stage lung cancer are more. The cure/ recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all. The primary determinant of prognosis in NSCLC is the stage at which the cancer is diagnosed. For non-metastatic cancers, however, it is the nodal status that determines the stage and hence the prognosis.

9. Prevention: Rightly said, prevention is always a better choice. Cigarette smoking is to be avoided by all means as it is the single major cause of lung cancer. Even exposure to cigarette smoke (passive or secondhand) is also an established cause of lung cancer and is known to increase the risk of lung cancer in non-smokers as well. Preventing exposure to secondhand smoke can be helpful in decreasing the incidence and mortality of primary lung cancers. Above-mentioned apart, other important risk factors such as exposure to ionizing radiation, environmental carcinogens like smoke from burning black tar, exhaust gases from automobiles, outdoor air pollution, and occupational exposure to asbestos, arsenic, beryllium, nickel, cadmium, chromium etc all too are known to increase the risk for lung cancer and mortality thereof. In fact, cigarette smoking is known to potentiate the effect and hence the lung cancer risk of many of the above-mentioned carcinogens, multi-fold, in smokers. Thus, either eliminating or reducing the exposure to the above-mentioned carcinogens can lead to a decrease in the risk of lung cancer and incidences thereof. Furthermore, randomized clinical trials indicate that high-intensity smokers (only) who take supplementation of beta-carotene have an increased risk/ incidence of lung cancer. Vitamin E supplementation, on the other hand, does not affect the risk of lung cancer as indicated by the trials.

Lung Cancer Awareness Month - Lung Cancer In Nutshell!

We live in an age where every single individual, more or less, is exposed to the risk of cancer. It is probably an unfavorable lifestyle we lead that deprives us of good health. This might alarm many but considerable changes in lifestyle can help you realize cancer as a preventable disease. Cancer does not only make you undergo severe suffering but it also affects your friends and family. The pallor of misery spreads wider than you think.

Abstain from tobacco: Consuming raw tobacco or smoking tobacco can be equally detrimental to your health. Tobacco increases your chances of contracting the disease. As is known, passive smoking can also affect your health adversely. Tobacco can be the potential cause behind cancer of the mouth, throat, larynx, lungs, oral cavity and even the pancreas. It might harm your kidneys and cervix. It is upon you to quit tobacco at the earliest possible. One should also try and persuade friends and relatives to give up smoking.
Drink alcohol in moderation: Complete abstinence from alcohol might not be possible if you have already been ushered into your work- life. The society might require you to be an occasional drinker. It is important to drink in moderation. Crossing the limit can propel consequences as serious as cancer of the stomach, pancreas, liver and the heart.
A balanced and nutritious diet: Deciding on a plant- based diet or a Mediterranean diet can aid your fight against the risk of cancer. A Mediterranean diet will involve green leafy vegetables, lots of fresh fruits, whole grains, mixed nuts, legumes and also the use of extra- virgin olive oil. Fish can be a safe bet but red meat should be avoided. One must also try to avoid processed meat as they tend to make you prone to the risk of cancer.
Immunization: Hepatitis B and HPV or Human papilloma virus vaccines are extremely necessary to protect you against the sexually transmitted types of cancer.
Sun protection: Caring for your skin doesn't arise from vanity. Skin cancer is one of the most prevalent kinds of cancer; the chances of this disease can be restricted by remaining in shade especially during midday, by wearing covered clothes and by using a good sunscreen lotion repeatedly while outside.
Exercise diligently: Did you think it was okay to have weaker muscles and bulging layers of fat? If yes, you probably have grown numb to the inadequacies you face in result. Unchecked fat can lead to obesity which further complicates health conditions. Metabolic activity differs from person to person. Regular exercising can help regulate metabolism according to the needs of your body. Physical exercise protects you against the risk of breast and colon cancer. Moderate or vigorous physical activity for 150 to 75 minutes a week respectively can reduce the risk of cancer.
