Breast Cancer Risk Assessment Calculator

Breast cancer is a cancer in which abnormal cells in the breast proliferate uncontrollably to form a mass of tissue called tumor. Breast cancer cells enter the blood and lymphatic capillaries and are carried to other parts of the body(1^✔).

Types of Breast Cancer -

Two types of breast cancer include ductal carcinoma (originates in the milk duct), the most common type, and lobular carcinoma (starts in the breast lobules/milk glands)(2^✔).

Certain breast cancer treatments include chemotherapy, radiotherapy, lumpectomy, and mastectomy(3^✔).

Do you know breast cancer can be treated and cured completely if detected early? Nearly 269,000 breast cancer patients die in low-income and middle-income countries due to late diagnosis.

Screening and Diagnostics for Breast Cancer -

As increasing age is the major risk factor for breast cancer, all women aged 40 years or more must take mammography every 1-2 years. Mammograms can be of 2 types – Screening and Diagnostic. Breast cancer screening is used for women with no signs or symptoms of breast cancer and can detect breast calcifications(4^✔).

Diagnostic mammography is used for women experiencing breast pain, lumps, and other signs of breast cancer or to assess the result obtained from a screening mammogram(5^✔).
