Am i having breast cancer? what should i do?

Go to your doctor!: Do not wait. Go see your doctor asap to have this evaluated. Most breast lumps are benign, but you should have this evaluated to make sure that it is not malignant. http://www.mayoclinic.com/health/breast-lumps/my00165.

Don't know your sxs.: Recommend medical evaluation. Breast cancer sx’s can include a mass. Masses that are painless, irregular ; hard are more suggestive of cancer but they can also be tender, painful ; soft. Swelling of breast; thickened, red, skin; non-milky nipple discharge; new retraction of nipple, puckering or irritation of skin or pain ; sometimes swollen lymph nodes under arm(s). You need in person evaluation.

See a Breast surgeon: There is inadequate information to provide specific advice but if there are any concerns that you may have about a breast mass then see a breast surgeon. You will likely start with having a mammogram or ultrasound, maybe a breast biopsy to rule out breast cancer.
