Breast cancer is an overgrowth of breast cells. we’d like to know how any cancer can develop.

Cancer occurs as a result of abnormal changes within the genes liable for regulating the healthy growth of cells. The genes act as the “control room” of every cell. in Normal, the cells in our bodies substitute themselves through an orderly process of cell growth: healthy new cells take over as old ones die out. But over time, mutations can “turn on” certain genes and “turn off” others during the cell. That changed cell gains the power to stay dividing without control or order, producing more cells a bit like it and forming a tumor.

A tumor is often benign (not dangerous to health) or malignant (has the potential to be dangerous). Benign tumors aren’t considered cancerous: their cells are on the brink of normal in appearance, they grow slowly, and that they don’t invade nearby tissues or spread to other parts of the body. Malignant tumors are cancerous. Left unchecked, malignant cells eventually can spread beyond the first tumor to other parts of the body.

The term “breast cancer” refers to a malignant neoplasm that has developed from cells within the breast. Usually, carcinoma either begins within the cells of the lobules, which are the milk-producing glands or the ducts, the passages that drain milk from the lobules to the nipple. Less commonly, carcinoma can begin within the stromal tissues, which include the fatty and fibrous connective tissues of the breast.

Over time, cancer cells can invade nearby healthy breast tissue and make their way into the underarm lymph nodes, small organs that filter foreign substances within the body. If cancer cells enter the lymph nodes, they will have a pathway into other parts of the body. The carcinoma ’s stage refers to how far the cancer cells have spread beyond the first tumor (see the Stages of carcinoma below for more information).

Breast cancer is usually caused by a genetic disease. However, only 5-10% of cancers are due to an abnormality inherited from your mother or father. Instead, 85-90% of breast cancers are due to genetic abnormalities that happen as a result of the aging process.

There are steps everyone can do to help the body stay as healthy as possible, like eating a diet, maintaining a healthy weight, not smoking, and exercising regularly. While these may have some impact on your risk of getting carcinoma, they can’t eliminate the danger.
