About 1 of every 9 Canadian women face a lifetime risk of developing breast cancer, 20%of cases are under 50 years of age; 80% are over 50.

About 90% of breast cancer arise in the glandular tissue, usually in a milk duct or a lobe.

Some breast cancers grow very slowly and remain localized for many years; others double in size every few days.

On average, however, breast cancers double in size about every 100 days, and may go undetected for several years.

Breast lump or thickening; change in breast shape, size, or symmetry, redness, pitting, dimpling, or inflammation of skin, clear or bloody nipple discharge; retraction or indentation of nipple.

Most breast cancers are not painful at first, but as the tumors grow and spread, they cause persistent breast tenderness or pain.

Severe pain results if the cancer spreads to the bone, lungs, and liver or other parts of the body.
