Hello. : Hello. I dont know if you have cancer. Most breast cancers aren't tender. Cancers usually don't grow tremendously quickly. However, it doesn't state how long the brown spot has been there. Possibly the brown spot might be a mole. I don't know if you are fair skinned or have had very much sun exposure. Please check the brown spot for the following. This information comes directly from the american academy of dermatology. Asymmetry: if the mole has asymmetry (one half is unlike the other half). Border: the border is irregular, scalloped or poorly defined. Color: the color is varied and has shades of tan, brown or black; is sometimes white, red or blue. Diameter: the diameter is more than 6 mm (the size of a pencil eraser). Evolving: a mole or skin lesion that looks different from the rest or is changing in size, shape or color. If you have an irregular mole that itches, bleed or is painful, that can be worrisome for possible skin cancer. I do recommend that this be evaluated. Normally, breast tumors are evaluated by general surgeons and possible skin cancers are evaluated by dermatologists. Because of the location, i recommend that you see a general surgeon. Take care.
