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!

It is perfectly normal for women to experience the periodic monthly bleeding cycle. However, if a woman experiences uterine bleeding which is abnormal and dysfunctional, it could be a symptom of infection. Other causes of abnormal uterine bleeding include hormonal imbalance, infection in cervix and cancer of the uterus. Many women can also experience abnormal uterine bleeding during first trimester of pregnancy.

The following are considered to be abnormal or dysfunctional uterine bleeding:

A menstrual cycles occurs between 21 to 35 days, anything shorter or longer than this is abnormal
No period for 3 6 months (amenorrhea) is abnormal
Spotting or bleeding between periods
Spotting or bleeding after intercourse
Bleeding that is heavier or lasts longer than usual
Spotting or bleeding after menopause
What can cause such a situation?

Some of the common causes leading to abnormal bleeding are as follows:

Miscarriage
Ectopic pregnancy
Pregnancy
Cervical or uterine infections
Fibroids
Hormonal imbalances
Problems with blood clotting
Polyps
Polycystic ovarian
Endometrial hyperplasia
Cancer of the reproductive tract
How to Diagnose it?

Most women tend to ignore abnormal bleeding, taking it as something to do with age or hormones. A detailed physical examination and history is done to understand menstrual cycle patterns and family history. In addition, the following would be used.

Ultrasound: The pelvic organs are examined through sound waves to locate the problem area
Hysteroscopy: Through a thin device that is inserted into the vagina, the doctor takes a look at the inside of the organs and identify the cause for the bleeding
Endometrial biopsy: The uterine lining tissue is removed and examined under microscope to look for tissue changes that could be causing the bleeding
How Best to Treat It?

This would depend on the reason for the abnormal bleeding. However, in most cases, combinations of the following are useful in treatment.

Hormone replacement can be done depending on the age and gynecological history, the type and the dose of the hormone would be decided upon. These could be in the form of tablets, vaginal creams, injections, or through an intrauterine device
Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are useful in reducing bleeding and controlling cramps during excessive menstrual bleeding.
Antibiotics may be useful if there is infection of the pelvic organs.
Polyps, cysts, cancers, and other growths can be removed via hysteroscopy and sent for biopsy to confirm they are not cancerous.
Endometrial ablation where the endometrial tissue is treated with heat can be used to control bleeding permanently.
Hysterectomy would be done if other forms of treatment have failed. This could depend on their gynecologic history and other considerations as she cannot get pregnant after this.
Do not ignore if you see a change in the pattern of your uterine bleeding. It definitely calls for medical attention and if identified early, can be managed in much simpler ways. 

Abnormal Uterine Bleeding - How Best to Diagnose It?

Breast cancer begins when the cells that are present in the breast start to go out of control. These cells generally form a tumor which can be seen on mammogram or one can feel it as a lump. The tumor is threatening if the cells can grow into the tissues that surround it or spread to other areas of the body. Breast cancer happens mostly in ladies. Here are a few methods with which you can prevent breast cancer-

Keep your weight in check: Maintaining a healthy weight is important for everyone although, it is easy to tune it out since it is said so often. Being overweight can expand the danger of a wide range of cancers, including breast cancer, particularly after menopause.
Be physically active: Women who are physically active for almost or at least 30 minutes a day have a lower danger of breast cancer. Normal activity is additionally one of the ideal approaches to keep weight under control.
Eat Your Fruits and Vegetables and Avoid Too Much Alcohol: A balanced and healthy diet can bring down the danger of breast cancer. Attempt to eat a considerable measure of fruits and vegetables and keep liquor at moderate levels or lower. While moderate drinking can be useful for the heart in most grown-ups, even low levels of intake can build the danger of breast cancer. If you do not drink, don't feel you have to begin. In case you drink modestly, there is less risk.
Try not to Smoke: Smokers and non-smokers alike know how undesirable smoking is. It brings down a person s quality of life and expands the danger of heart and lung diseases, stroke, and no less than 15 types of cancer, including breast cancer. It additionally causes bad breath, awful teeth, and wrinkles.
Breastfeed, If Possible: Breastfeeding for almost one year or more brings down the danger of breast cancer. It additionally has extraordinary medical advantages for the baby as well, especially in terms of immunity.
Keep away from Birth Control Pills: Contraceptive pills have both dangers and advantages. In many cases, the more young a lady is, the lower the danger is. While ladies are taking birth control pills, they have more chances of falling prey to breast cancer as per various medical studies. This danger leaves rapidly in the wake of stopping the pill. The danger of stroke and heart attack is increased while on the pill, especially if the woman smokes. Long term use can likewise have essential advantages, such as bringing down the danger of ovarian cancer, colon tumor and uterine cancer and undesirable pregnancy. In case you are exceptionally worried about breast cancer, staying away from birth control pills is also an alternative to lower the risk.

Breast Cancer - 6 Ways You Can Prevent It!

Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.

Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.

What Causes Lung Cancer?

The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.

Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).

Lung Cancer Symptoms

Early symptoms and signs of lung cancer

There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:

Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
Fatigue: It is common to feel weak or excessively tired.
Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer

Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:

Bone pain
Swelling of the face, arms or neck
Headaches, dizziness or limbs that become weak or numb
Jaundice
Lumps in the neck or collar-bone region
Treatment

Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.

Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.

Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

Lung Cancer: Causes, Symptoms and Treatments

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps).

Uterine polyps range in size from a few millimeters - no larger than a sesame seed - to several centimeters - golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

You can have one or many uterine polyps. They usually stay contained within your uterus, but occasionally, they slip down through the opening of the uterus (cervix) into your vagina. Uterine polyps most commonly occur in women who are going through or have completed menopause, although younger women can get them, too.

Symptoms

Signs and symptoms of uterine polyps include:

Irregular menstrual bleeding - for example, having frequent, unpredictable periods of variable length and heaviness
Bleeding between menstrual periods
Excessively heavy menstrual periods
Vaginal bleeding after menopause
Infertility
Some women have only light bleeding or spotting; others are symptom-free.
When to see a doctor
Seek medical care if you have:

Vaginal bleeding after menopause
Bleeding between menstrual periods
Irregular menstrual bleeding
Causes

Hormonal factors appear to play a role. Uterine polyps are estrogen-sensitive, meaning they grow in response to circulating estrogen.

Risk factors

Risk factors for developing uterine polyps include:
Being perimenopausal or postmenopausal
Having high blood pressure (hypertension)
Being obese
Taking tamoxifen, a drug therapy for breast cancer
Complications

Uterine polyps might be associated with infertility. If you have uterine polyps and you're unable to have children, removal of the polyps might allow you to become pregnant, but the data are inconclusive.

Uterine Polyps - Symptoms, Causes & Complications Related To It! 

The treatment options for bone cancer depends on the type of cancer one is suffering from, the general health of the patient, the stage of cancer and the general preference of the patient. Different treatment options are designed for different types of cancer, based on the diagnosis. Each treatment responds in a different way. An oncologist decides the treatment options considering all the factors mentioned above. For instance, some cancer is best suited to surgery, while some cancer needs radiotherapy or chemotherapy to curb them. In many cases, all three modes of treatment might be required to tackle the growth of the cancer cells.

Surgery:
The goal of surgery is to eradicate the cancer cells in totality along with some surrounding healthy tissues. This involves special techniques to remove a tumor in one piece. Following are the types of surgeries that are available:

Removing the cancer cells sparing the limb: At the very first sight, the surgeon tries to understand whether it is possible to separate cancer cells from the tissues and the nerves. If the same is possible, the surgeon tries to save the limb while getting rid of the cancer cells. For the sake of safety and to ensure that the surgery is effective, the surgeon removes some of the healthy bone from the body and may replace the same with tissue from other parts of the body. To achieve this, a doctor might seek the help from of a bone bank or use a special metal prosthesis.
Surgery that does not involve the limbs: If the bone cancer does not involve the legs and the arm, surgeons can remove the affected bone along with some healthy bone from the surrounding areas. Cancer of the ribs and the spine are good examples of this type.
Surgery that affects the limb: Bone cancer that has spread to a significant extent and is strategically located in such areas that it is very difficult to remove, requires amputation. While this form of treatment is being increasingly discouraged by the wider medical community, it still does exist. In such cases, patients are fitted with artificial limbs and trained to do their job without the use of natural limbs.
Chemotherapy:
This is a form of drug treatment that uses powerful chemicals to kill cancer cells throughout the body. This medication is mostly given through an IV and the medication kills whatever cancer cells it comes across. 

Radiation therapy:
Radiation therapy involves the usage of special X-ray beams that have high power and can kill cancer cells. The patients are required to lie on a table, while a machine moves around the affected area and treats it with high energy X-rays, thereby killing the cancer cells. Radiation therapy is often used in conjunction with chemotherapy to reduce the size of a tumor before operating on it.
