Should i be worried about this rash on my breast?

hello
okay so heres the deal my best size is 34 D yeah there kinda big well yesterday morning when I got in the shower I noticed a hug red rash looking thingy on the side of my left cha cha I thought maybe I slept on it funny but when I touched it...

it was extremely rough and felt like something hard and round was under the skin?? I showed it to a few friend and there were like yeah thats not normal? they have been joking around bout best cancer? but I no its not. I think that maybe a bused it and its just a blood clot I do hurt myself quite often without even noticing. any who my question for you is should I be worried or not??

lol... its not cancer... breast cancer doesn't show up as a RASH. Maybe you got a spider bite in your sleep.

humm a spider bite? haha ive had on of those the bump would be outside the skin not under. not nearly this big. My mom looked at she doesn't think its normal.
I also think its not cancer but im telling you that my friend are joking bout it cuzz that how odd it is.

Well... maybe it was... a BIG spider...

If it doesn't clear up within the next few days, go get it checked out by a doctor. They know what's up. You may have easily bruised it, it is a very tender area after all! Whatever you feel underneath may be swelling if you did bruise it. But if there is a rash.. hmm, hard to say, it could be some kind of bite though. Do you have any allergies?

Any changes in breast appearance should be checked out... lumps, bumps, swelling, rashes, skin discolouration etc. Its probably nothing to worry about but if it doesn't go away please get it checked out.

YEA SAT STUFF IS NASTY DNT TAKE IT PERSONAL MAYBE U SHOULD SEE A DOCTOR

You are wrong. there is a breast cancer that sounds just like she was saying!! Called inflammatory breast cancer the most deadly kind of Cancer there is. Most people don't know about it and it has been killing more and more woman!!! Even as young as 16.

LOOK FOR
Swelling, usually sudden, sometimes a cup size in a few days

Itching

Pink, red, or dark colored area (called erythema) sometimes with texture similar to the skin of an orange (called peau d'orange)

Ridges and thickened areas of the skin

What appears to be a bruise that does not go away

Nipple retraction

Nipple discharge, may or may not be bloody

Breast is warm to the touch

Breast pain (from a constant ache to stabbing pains)

Change in color and texture of the areola

I read an artical about breast cancer, and a rash in the area is a symptom of breast cancer:

What to look out for
Changes that could be due to a breast cancer are

A lump or thickening in an area of the breast
A change in the size or shape of a breast
Dimpling of the skin
A change in the shape of your nipple, particularly if it turns in, sinks into the breast or becomes irregular in shape
A blood-stained discharge from the nipple
A rash on a nipple or surrounding area
A swelling or lump in your armpit
