Breast Cancer

Breast cancer is cancer that forms in the breast cells. Breast cancer can occur in women and in men, but far more common in women. After skin cancer, breast cancer is a common cancer in women.

Breast cancer is another type of cancer that occurs in the breast tissue. When abnormal cells divide out of control, they can be great with an extra network form, or tumor, can be benign or malignant. Benign tumor cells do not spread to other body tissues, usually can be removed and will not recur.

Malignant tumor cells (cancer) can spread to nearby tissues of the body and detach from the primary tumor to form secondary tumors form anywhere in the body.

There are several common types of breast cancer:
• infiltrating / Invasive Ductal Carcinoma (IDC) occurs in 65 to 85 percent of breast cancer cases. Beginning in the milk duct cells and can penetrate the walls of the channel to attack the fatty tissue. Can be spread by blood or lymph. With a mammogram (X-ray photography) is usually seen as a network of unusual, small spots or both. It comes as a lump usually feels harder than the surrounding tissue.

• infiltrating / Invasive Lobular Carcinoma (ILC) occurs in 5 to 10 percent of breast cancer cases. There is the milk-producing glands and can spread to fatty tissue and elsewhere on the body. With a mammogram, it can look like IDC, but the physical examination usually does not find any hard lumps - network rather samara thickness. May occur more than one place in the chest or in both breasts simultaneously.

• Three subtypes are slow-growing invasive Medullary, Mucinous and Tubular carcinomas. That simultaneously occurred in 12 percent of breast cancer cases. They can be known to be better than other malignant cancers.

• Inflammatory carcinoma is a subtype of IDC. Having the characteristics of the breast becomes red, swollen and hot, and the skin thicken and may form small lumps. This occurs because of rapid cancer growth and clog lymph tissue. In 90 percent of cases, the cancer has spread to the lymph tissue when diagnosed. This is an aggressive cancer and generally taken care of by chemotherapy. Swelling of cancer occurs in one out of four percent of the cases.

• Paget's disease begins in the milk ducts and can be spread on the nipple and areola, causing hardening. If there are no lumps are felt, and biopsy showed no malignant cancer, it's a good sign. The Treatment with other malignant cancers.

• soft tissue tumors: tumors can occur in the supporting tissues of the breast. These tumors are the type that are not public.


Signs and symptoms of breast cancer include:

• A lump in the breast or thickened and feels different from the surrounding tissue
• Exit the blood on the nipple
• Changes in the size or shape of the breast
• Changes in the skin of the breast, such as dimples
• Form an inverted nipple
• Exfoliation nipple
• Redness of the breast skin, such as orange peel

Causes & Risk Factors


It is unclear what causes breast cancer. Doctors know that breast cancer occurs when some breast cells begin growing abnormally. These cells divide faster than cells in general. The accumulation of these cells to form tumors that can spread to the breast, lymph tissue or other body parts.

Breast cancer most commonly begins in the milk production line. Doctors call this type of cancer is invasive ductal carcinoma cancer. Breast cancer can also be started from the lobules (invasive lobular carcinoma) or the cells in the breast.

Scientists identify things that can increase your risk of having breast cancer. But it is not clear what why some people do not have risk factors develop cancer, while others who have risk factors never experienced. Looks like breast cancers are caused by a combination of genetic factors and the environment.

Breast cancer is hereditary

Doctors estimate that 5 to 10 percent of breast cancer is related to a genetic mutation in generations in the family. A number of inherited defective genes that may increase the likelihood of breast cancer have been identified. The common is breast cancer gene 1 (BRCA1) and breast cancer gene 2 (BRCA2), both of which increase the risk of breast cancer and ovarian cancer.

If you have a record of strong family with breast cancer or other cancers, blood tests may help identify defective BRCA or other genes that are present in the family.

Risk factors

The risk factor is anything that makes you more likely to develop breast cancer. But it does have one or even several risk factors does not mean you will develop cancer - some women with breast cancer do not have any known risk factors than other women.

Some things that can increase the risk of breast cancer include:

• Women. Women more likely to develop breast cancer than men.

• Increasing age. Your risk of developing breast cancer increases with age. Women over the age of 60 years have a greater risk than women with a younger age.

• Personal notes with breast cancer. If you have cancer in one breast, you have an increased risk of developing cancer in the other breast.

• Family history of breast cancer. If you have a mother, sister or daughter with breast cancer, you have a greater chance of being diagnosed with breast cancer. But in general those who have breast cancer have no family history of breast cancer.

• Gen offspring that increases the risk of cancer. Specific gene mutation that increases the risk of breast cancer can be decreased from parent to child. Mutations of genes in question are BRCA1 and BRCA2. These genes may increase the risk of breast cancer and other cancers, but they do not make cancer inevitable.

• Exposure to radiation. If you are receiving treatment with radiation to the chest as a child or young adult, you are more likely to develop breast cancer later in life.

• Obesity. Overweight or obese increases your risk of getting breast cancer.

• Coming months starting at a younger age. Future months that began before age 12 increases the risk of breast cancer.

• Menopause that begins at an older age. If you are starting menopause after age 55, you will have more chances of developing breast cancer.

• Having a first child at an older age. Women who have had children after the age of 35 can increase the risk of breast cancer.

• postmenopausal hormone therapy. Those who use hormone therapy treatment that combines estrogen and progesterone to treat the signs and symptoms of menopause have an increased risk of breast cancer.

• Drink alcohol. Drinking alcohol can increase the risk of breast cancer.


At this time of breast cancer can not be prevented, but can be diagnosed earlier than ever before. Early diagnosis possible with routine mammography and early examination of the suspected injury. The earlier cancer is unknown, the greater the chance for cure.

Here is a possible way to help prevent breast cancer:
• Low-fat diet (less than 20 percent), with enough fruit and vegetables, and maintain a healthy weight.

• When the cancer is found and treated early, there will be more treatment options that can be taken and have a better chance to heal.

• Among the clinical check-ups, do breast self-exam (BSE) monthly. Every woman's breasts are different, and change with age, menstrual cycle, pregnancy, menopause, or the use of birth control pills or other hormones. It may be normal if your breast feels a lump, swelling or tenderness at specific times, such as before the pregnancy.

• Breastfeeding may be slightly lower the risk, especially if it continues for 18 to 24 months. Vigorous exercise at a young age can give long protection. Even mild physical activity in adulthood can reduce the risk.
