Breast cancer genetics

Breast cancer is a hereditary disease. About 5 to 10% of breast cancer cases are caused by disordered genes. Breast cancer genetics deals with the study of hereditary genes and their characters and different mechanisms of transfer of traits from one generation to another.

Breast cancer medicine

Breast cancer medicine are drugs used to reduce risk of breast cancer in women, They prevent the breast cancer by acting as hormone blocking agents such as tamoxifen and aromatase, damaging cancer cells dna, or by using monoclonal antibodies like Trastuzumab.

Breast cancer mutations

Breast cancer mutations are mutations in two Breast cancer associated genes known as BRCA1 and BRCA2. BRCA genes normally prevent cancer, Every cell in the body has two BRCA1 or BRCA2 genes woman with defective BRCA genes are more prone to develop Breast cancer in early stages.Other mutations of genes like P53, ATM genes may increase risk of breast cancer.


Mammogram is a diagnostic technique used to screen breast cancer. It is a X-ray of Breast. it is used to detect tumours in early stages and to treat breast cancer.

Breast Biopsy

Breast Biopsy is a diagnostic technique used for confirmation of breast cancer. A breast biopsy is the removal of breast tissue and cells are examined under microscope for signs of cancer. There are three types of breast biopsies Fine-needle aspiration,Core biopsy,Open excisional biopsy.

Atypical hyperplasia

Atypical hyperplasia is a precancerous condition of accumulating abnormal cells in the breast. People diagnosed with Atypical hyperplasia had more risk of getting noninvasive or invasive breast cancer. Anti-estrogen medication(tamoxifen) reduces the 50% risk of breast cancer in women with atypical hyperplasia.
