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!

Breast cancer begins when cells in the breast(s) start to grow out of control. It is understood as being the most common cancer, seen predominantly in females, globally. It is reasonably treatable and often curable.

1. Type: Adenocarcinomas constitute more than 95% of breast cancers with infiltrating ductal carcinoma (IDC) being the most common form of invasive breast cancer.

Frequently occurring breast cancers present as one of the following types mainly

1. Ductal Carcinoma In Situ (DCIS): Is the most common type of non-invasive breast cancer and is confined to the milk ducts of the breast. There is no invasion in the basement membrane. Pure DCIS metastasizes rarely. Non comedo cribrioform carcinoma is the most common DCIS found which, when compared to the comedo type, is mostly non-aggressive.

2. Infiltrating Ductal Carcinoma (IDC): Represents majority (about 3/4th) of the breast cancers, and is known to metastasize commonly to bones, lungs and liver.

3. Lobular Carcinoma In Situ (LCIS): Develops in multiple lobules of the breast (bilaterally). LCIS is less commonly seen, compared to DCIS.

4. Infiltrating Lobular Carcinoma (ILC): Represent about a tenth of all breast cancers and tends to metastasize to other regions of the body.

Less commonly occurring breast cancers such as

5. Inflammatory Breast Cancer: Is relatively uncommon and are caused probably owing to viral infections. The breast is warm, red and swollen.

6. Paget s disease of the nipple: Is a rare form of breast cancer. It begins in the milk ducts and spreads to the nipple and areola.

7. Medullary Carcinoma

8. Mutinous Carcinoma

9. Tubular Carcinoma

10. Phylloides tumor etc all.

2. Gender: Affects the female populace predominantly. However, a small percentage of breast cancer is attributable to the male populace as well.

3. Etiology: No definite cause is known. However, diet, lifestyle, environment, hormonal/ reproductive factors, personal or family history of breast cancer especially in first degree relatives and also any benign breast disease history etc all are known to increase the risk of breast cancers. Specifically, excessive fatty diet, obesity, type 2 diabetes mellitus, benign breast disease, heredity/ inheritance of mutated breast cancer genes 1 (BRCA1) and 2 (BRCA2), smoking, alcohol intake, infertility, estrogen therapy/ hormone replacement therapy (long term) in post menopausal women, delayed age at first pregnancy, nulliparity (not having child), early menstruation, delayed onset of menopause, lactating mothers not breast feeding, exposure to ionizing radiation, sedentary lifestyle, depression, exposure to MMTV virus etc all can potentially increase the risk for breast cancer.

4. Features: Signs & symptoms, of breast cancer, manifest majorly in the following ways

Lump/ nodule in the breast that gets attached to the skin of the breast over time. The lump / nodule could be hard and painless with irregular edges or it could also be soft, rounded, tender and painful.

Enlarged lymph nodes in the axilla which are palpable.

Swelling of whole or a part of a breast. This is even if there is no distinct lump felt.

Retraction or thickening of the nipple(s).

Pain in the breast or nipple.

Discharge from nipple other than breast milk.

Irritation/ scaliness of skin over the breast.

Redness of nipples

Rarely, red, swollen and tender breast.

5. Screening: Is generally recommended for asymptomatic populations goal of which, as usual, is to be able to detect & diagnose breast cancer at an early stage which is potentially curable. It is mostly radiologic with mammography/ USG being instrumental in raising suspicions for further diagnostics (i.e. biopsy) that help detect breast cancer, if any, early.

6. Diagnosis: A self-examination/ clinical exam of the breast(s)/ axilla that reveals a palpable mass prompts the following diagnostics. Abnormal blood test results may be indicative of malignancy, but a follow up imaging/ biopsy is always the gold standard for accurate diagnosis.

Blood: ER/ PR/ HER2/neu, uPA, PAI-1, CA15-3, CA27.29 etc all tumor markers are helpful.
Imaging: Mammography/ USG Scan usually, as relevant. Again, CT Scan of abdomen & pelvis and chest, PET CT scan, bone scan etc all help detect metastasis, if any, for cancers in stage III & above.
Biopsy: either excisional, incisional, fine needle aspiration (FNA) or core biopsy technique, as contextually appropriate, is frequently employed and a histopathological examination (HPE) thereof clinches the diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, radiotherapy, hormone therapy/ chemotherapy as deems 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 is key for an effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for an early stage breast cancer are more. The cure/ recovery chances are influenced by the type, grade, stage of cancer, recurrence and the patient s general health & vitality etc all. Above-mentioned apart, age, menopause status, lymph node status, ER/ PR/ HER-2/ neu status, size & extent of breast cancer etc all also influence the treatment outlook in breast cancer. The five year survival rate is strongly correlated with the stage of breast cancer.

9. Prevention: Rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an increased focus on protective factors and avoidance of the risk factors can be of help. An adherence to a Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising (for at least 30 minutes daily), de-stressing and relaxation is highly recommended for reducing the risks of breast cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. It is advisable to limit milk/ dairy, preferably of low fat content, to 1 to 2 servings max daily. Although alcohol is optional and is not for everyone, the consumption of the same, if any, has to be strictly in moderation, and is best avoided. Smoking is to be avoided as well. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly or are best avoided too. Limiting dosage/ duration of hormone therapy, if any, especially to counteract post menopausal symptoms and also avoiding exposure to radiation and environmental pollution can help reduce the risks of breast cancer. Apart from the above-mentioned, for high risk cases, a prophylactic oophorectomy, prophylactic radical mastectomy, long term hormone therapy etc all can help reduce the chances/ risks of developing breast cancer significantly. Breastfeeding is known to confer protection against breast cancer risk too.

Breast Cancer - In A Nutshell

Breast cancer is one of the most common cancers in women about 1 in 8 women in the USA  develop invasive breast cancer. The incidence of breast cancer has increased with changes in lifestyle including smoking, drinking and loss of physical activity. The risk factors are age, ethnicity and family history cannot be changed. However, there are some risk factors that can definitely be acted upon to reduce the chances of developing breast cancer.

Weight management: Obesity is one of the major risk factors for breast cancer and managing weight and a good body mass index will help reduce the risk of developing breast cancer. This is especially important in women undergoing menopause.
Reducing smoking: The benefits of quitting it are manifold and reducing the risk for breast cancer is one of them. This will, as a byproduct, also result in a host of other benefits including improved quality of life, reduced chances of heart disease, stroke, and other cancers.
Physical activity: In addition to helping in weight management, this also helps reduce the risk of breast cancer. Ideal recommendation is 30 minutes of physical activity per day, plus strength training.
Breastfeeding: This helps in reducing the risk of breast cancer. Prolonged feeding is shown to have a greater protective benefit.
Hormone replacement therapy: When possible, limit the use of hormone replacement therapy for prolonged periods of time. Explore options of non-hormonal substitutes or use the least permissible or required dose. Be sure to get periodic check-ups when on hormone therapy.
Reduce exposure to environmental pollution: Higher levels of pollutants are linked to a higher incidence of breast cancer. When possible, avoid getting exposure to environmental pollutants.
Screening: If there is a strong family history or other risk factors, then screening can help detect breast cancer very early in the process. Recommended ages for mammography are as follows:
If you are age 40   44: Go for annual mammograms after discussing risks and benefits with the doctor.
If you are age 45   54: Go for annual mammogram.
If you are age 55 or over: Mammograms are recommended every other year. You can choose to continue to have them every year. Self-breast exams are not sufficient. However, if being done, they can also be an input to an abnormality.
Cautious use of birth control pills: Birth control pill usage to be discussed with your gynaecologist if you are above 35 years of age and smoke. The good news is that the risk associated with it disappears slowly after the pill is stopped.
These will help reduce the risk of developing breast cancer, early detection, and improved prognosis.

Breast Cancer - 8 Things You Must Do To Avoid it!

Breast cancer is a form of cancer which develops from the breast tissue. Breast cancer is indicated by signs such as a lump in the breast, changes in breast shape, fluid flowing from the nipple, dimpling of skin, or the development of red scaly patches. Breast cancer is a fatal form of cancer in women and immediate diagnosis is required on observing the symptoms.

Diagnosis of breast cancer
Other than the regular breast screening, the diagnosis of breast cancer involves the following steps and methods:

Seeing your general practitioner (GP): It is very important to visit your GP soon after noticing the symptoms of breast cancer. Your GP will examine you properly and in case your symptoms need more assessment, he/she will refer you to a breast cancer clinic.
Mammogram and breast ultrasound: You will be required to have a mammogram, as recommended by a specialist breast unit. This is an X-ray of the breasts. An ultrasound scan may also be required. Breast ultrasound should be undertaken only if you are less than 35 years of age. This is because, young women have denser breasts and a mammogram is not as effective as ultrasound in the diagnosis of breast cancer. In ultrasound, high frequency sound waves are used for obtaining an image of your breasts. It is observed to notice any abnormality or lumps. A breast ultrasound is also important for determining whether a lump is solid or contains liquid.
Biopsy: In this diagnosis process, a sample of the tissue cells is taken from the breasts and tested under a microscope to find out if it is cancerous. A scan and needle test for the lymph nodes present in your armpit is also done to check whether they have also been affected. A biopsy is undertaken in several ways, depending upon the condition and severity. A needle aspiration biopsy is used for testing a sample of your breast cells without the removal of the tissues. This is the most common form of biopsy and it is also used for draining a small fluid-filled lump or benign cyst. During the process, you will be given a local anesthetic. Usually, a needle biopsy is carried out guided by an X-ray, ultrasound and an MRI scan as well. This helps in distinguishing it from non-invasive changes such as ductal carcinoma in situ.
Another form of biopsy used for the diagnosis of breast cancer is called vacuum assisted biopsy or mammotome biopsy. In this process, a needle gets attached to a suction tube, which helps in obtaining the sample and for clearing the bleeding.

How Is Breast Cancer Diagnosed?

Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. It occurs in both women and men, although breast cancer in men is rare.

Risk factors:

Lack of physical activity
Alcohol consumption
Advancing age
No childbirth or no breastfeeding
Family history of breast cancer
Early menarche (< 12 years of age) or late menopause ( > 55 years of age)
History of ovarian cancer or endometrial cancer
History of benign breast conditions (e.g. atypical hyperplasia) or lobular carcinoma in situ
Receiving hormonal replacement therapy (HRT)
History of receiving radiation therapy to the chest before age of 30
More importantly, you can lower your risk of having breast cancer by the following measures:

 Have regular physical activities, do at least 150 minutes of moderate-intensity aerobic physical activities per week (e.g. climbing stairs or brisk walking)
Avoid alcohol drinking;
Maintain a healthy body weight and waist circumference - aim for a body mass index (BMI) between 18.5 and 22.9, and a waist circumference of not more than 80cm for women; and
Have childbirth at an earlier age and breastfeed each child for longer duration factors include:
What are the common symptoms of breast cancer?

The symptoms of breast cancer may not be easily noticed at an early stage. Any of the following changes in the breast can be a symptom of breast cancer:

  Breast lump;

  A change in the size or shape of the breast;

  A change in skin texture of the breast or nipple (e.g. red, scaly, thickened or  orange-skin  appearance);

  Rash around the nipple;

  In-drawing of the nipple;

  Discharge from one or both nipples;

  New and persistent discomfort or pain in the breast or armpit; and

  A new lump or thickening in the armpit

What is breast cancer screening? Should I screen for breast cancer if I do not have any symptom?

Screening means examining people without symptoms in order to detect disease or fi nd people at increased risk of disease. It is often the fi rst step in making a defi nitive diagnosis. For breast cancer screening, its purpose is to fi nd women who have breast cancer, before they have any symptom, in order to offer them earlier treatment.

Mammography is widely used as a screening tool. It is an X-ray examination of the breasts. During mammography, the breast is pressed between 2 plates to flatten and spread the breast tissue, in order to obtain a clear image. Some women may find it uncomfortable or painful but the discomfort is usually short lasting. Mammography screening is safe in general and only a very small dose of radiation is used in the procedure. One in 5 female breast cancer patients may be missed by mammography.

Prevention and Screening for Breast Cancer: Information for women and their families

Breast cancer is the form of cancer that occurs from breast tissues in women. Signs of breast cancer may include a lump in the breast, changes in the shape of the breast, dimpling of the breast skin, a fluid coming out of the nipples or development of red scaly patches on the skin. There might be pain in the bones, swollen lymph nodes, shortness of breath, or the skin turning yellow and pale.

Breast cancer is a fatal mode of cancer in women, and one must try to abstain from this cancer in all possible ways. Here are 5 ways you can decrease the risk of breast cancer.

1. Keeping a check on your weight: although the process is tough to maintain, keeping up a sound and healthy weight is a critical objective for everybody. Being overweight can expand the danger of a wide range of cancers, including breast cancer, particularly after menopause in women. Exercise is very important for maintaining a healthy body and lifestyle. Women who exert physically regularly are fitter than others and are at a much lower risk of acquiring diseases of any kind. Regular exercise decreases the chance of getting breast cancer and also keeps the body weight in check.

2. Maintaining a healthy diet: maintaining a healthy and balanced diet is a key for keeping away from any kind of cancer or major health problem. Include a sufficient amount of fresh fruits and green vegetables in your daily diet to ensure the supply of all vital nutrients to your body. This would increase your immunity.

3. Avoid smoking and consume less alcohol: smoking is a very unhealthy and harmful habit. Smoking lowers the quality of your life, and causes numerous diseases. Heart diseases, stroke and many kinds of cancer, including breast cancer can be caused from smoking. If you drink alcohol, you should moderate your drinking habits and drink less, as drinking in excess may lead to breast cancer.

4. Practice breast feeding: breast feeding your children for a span of one year or more is likely to reduce the risk of breast cancer.

5. Avoid taking birth control pills: birth control pills, in spite of having several benefits are associated with risk factors as well. Birth control pills have got worse effects in younger women than older aged women. Using birth control pills may cause breast cancer and these pills should be avoided.

There are many ways, adapting which you can lower the chances of getting breast cancer.
