I don't know the difference between "normal" breast lumps and cancerous ones. When should I become concerned?

I don't know the difference between "normal" breast lumps and cancerous ones. When should I become concerned?

Hard to tell: It is hard to tell which lumps are benign and which ones are cancer on physical exam. It is best for women to perform monthly breast exams and to know what their breasts feel like. If there are lumps, I tell my patients "know your lumps". If there is a change in the exam on a monthly basis, then you need to see your doctor. The only way to know for sure if lump is cancer is through testing and biopsy. ...Read more

Is there a difference between having a movable and non-moving breast lump at the age of 15 in terms of cancer?

Is there a difference between having a movable and non-moving breast lump at the age of 15 in terms of cancer?

Yes: Generally, a non-movable lump indicates inflammation around it. That means that the body's immune system has recognized it as "foreign." any lump of concern to you, moveable or not, should be checked out by your doctor. Sometimes, it's only normal anatomy that you're feeling. Btw, congratulations for doing self breast examination. If you don't know what that is, discuss it with your doctor. ...Read more

Found a lump on my breast but I am breastfeeding, what's the possibilities of a benign cancer?

Usually benign lump: Women who are breastfeeding may find lumps in their breast and this can be scary. When in doubt always have it checked by your doctor.

How can I tell if a breast lump is cancer or a benign lump?

How can I tell if a breast lump is cancer or a benign lump?

Is cancerous breast lump single or there may b two cancerous lumps in breast.?

Multiple possible: Hi. If you have a genetic risk for breast cancer (e.g., one of the BRCA gene mutations, and other genes too), multifocal breast cancer is more likely than in sporadic cases of breast cancer. Overall, multifocal breast cancer at the time of diagnosis is uncommon. Given your age of 25, I would lean heavily toward suspecting a genetic form of breast cancer. Evaluate ALL breast lumps. Good luck! ...Read more

Woud you please discuss the characteristics of cancerous lumps?

Not easy to say: Tumors, be it benign or malignant, are often painless so I'm not sure you can tell without a biopsy. If a lump grows very fast or develops smaller nodules around it, I guess that would be suspicious of a malignancy but even so you can't tell for sure without tissue. If you have any suspicious lesion, especially if it popped up recently, have your doc take a look at it. ...Read more
