(a) Ductol carcinoma: It occurs in about 85-90% of the cases.

(b) Lobular carcinoma: It occurs in about eight percent of cases.

The ductal carcinoma arises in the ducts, that is, the passageway which carries milk from the milk producing lobules to the nipple. While lobules carcinoma arises in the lobules, that is, part of the lobe, which ends in dozens of tiny bulbs that can produce milk.

Causes of breast cancer

(a) Hereditary risk: It has been known that women whose mothers or sisters had breast cancer have a higher risk of developing the disease themselves.

(b) Hormonal risk factors: The female hormones estrogen and progesterone are involved in breast cancer formation. For eg it is known that women who start to menstruate at an early age or who have a higher risk of breast cancer than woman who do not.

In case of Breast-sparing surgery or partial mastectomy, the cancerous lump is removed but not the entire breast. But in case of Mastectomy, the entire breast is removed. It is done if the tumour is too lage to be removed without removing the entire breast.

Radiation Therapy uses high-energy rays to damage cancer cells and stop them from growing. Radiation is used after breast conserving surgery to reduce the risk of the cancer returning in the breast.

Systemic Treatment: Chemotherapy drugs are medications that kill rapidly growing cells such as cancer cells. These drugs can or intravenously. Chemotherapy medications are very powerful.
