Causes of Breast Cancer in Most Females

Breast cancer occurs because the cells in the breast grow abnormally and uncontrollably. These cells divide rapidly and gather to form lumps, then can spread to the lymph nodes or to other organs.

Not yet known what causes these cells to turn into cancer cells, but experts suspect that there is an interaction between genetic factors with lifestyle, environment, and hormones, so that cells become abnormal and grow out of control.

Currently several symposiums are often held to discuss breast cancer, among others, the Annual San Antonio Breast Cancer Symposium, The History Annual of the San Antonio Breast Cancer Symposium can see in this article.

Doctor Diagnosis

Doctors know that breast cancer occurs when some breast cells begin to grow abnormally. These cells divide more rapidly than healthy cells do and continue to accumulate, forming a lump or mass. Cells may spread (metastasize) through your breast to your lymph nodes or to other parts of your body.

Breast cancer most often begins with cells in the milk-producing ducts (invasive ductal carcinoma). Breast cancer may also begin in the glandular tissue called lobules (invasive lobular carcinoma) or in other cells or tissue within the breast.

Researchers have identified hormonal, lifestyle and environmental factors that may increase your risk of breast cancer. But it's not clear why some people who have no risk factors develop cancer, yet other people with risk factors never do. It's likely that breast cancer is caused by a complex interaction of your genetic makeup and your environment. The sign and indication of breast cancer the easiest to see is the presence of a lump in the breast

Causes of Breast Cancer in Most Women

1. Smoking and alcohol consumption

Causes of Breast Cancer in Most Females

Smoking has been shown to increase the risk of developing various cancers, including breast cancer. The same is true for the habit of excessive alcohol consumption. The more consumption of cigarettes and alcohol, the higher the risk of breast cancer.

2. Risks increase with age

Women older than 55 have a greater risk than younger women.

3. Have been exposed before

If you have had breast cancer in one breast, you have an increased risk of developing breast cancer.

4. Family history of breast cancer

If you have a mother, sister or female child with breast cancer, you have a greater chance of being diagnosed with suffering. However, most people diagnosed with breast cancer do not have a family history of the disease.

Approximately 20%-25% of breast cancer patients have a positive family history but only 5%-10% of breast cancer cases demonstrate an autosomal dominant inheritance[1].

5. Inheriting genes that increase cancer risk

Certain gene mutations that increase the causes of breast cancer can be derived from parents to their children. The most common gene mutations are referred to as BRCA1 and BRCA2. This gene can increase the risk of causing breast cancer and other cancers.

6. Radiation exposure

If you receive radiation treatment for the chest from childhood or young adulthood, you are more likely to develop breast cancer later on.
