What does breast cancer feel like? is it painful?

No pain: It takes at many years for a breast cancer to reach 1cm, about 1/2inch. Early detection is very important; yearly screening mammogram starting at the age of 40, monthly self breast exam and yearly physical exam by your doctor is recommended to detect early stages of breast cancer, with excellent prognosis. Palpable breast cancer is painless, firm, usually is not moveable, with retraction of skin.

Firm mass: Most malignant lesions of the breast can be felt at 1/2 cm. in size. Palpation of breast with hand behind head on side of palpation using opposite hand with fingers moving in a clockwise direction will detect a firm solitary mass different than any other lesions or lumps. The mass is very firm and non tender. Should be biopsied even if not detected on follow up mammo.
