What Does a Breast Cancer Lump Feel Like?

23

Although breast cancer is the most common cancer found in women, most breast lumps are not cancer. In fact, more than 80 percent of them end up being benign. But can a woman tell if a breast lump is cancer?

in a small percentage of women, a painful breast lump turns out to be cancer.

While the majority of lumps are benign, experts at the Susan F. Smith Center for Women’s Cancers say it is important for women to speak with their doctor if they notice changes to their breasts.

In general, cancerous lumps tend to be more irregular in shape. They may also feel firm or solid, and might be fixed to the tissue in the breast. They are also often painless. However, in a small percentage of women, a painful breast lump turns out to be cancer.

Cysts, which are fluid-filled lumps, are common in the breast and are benign. They form when fluid builds up inside breast glands, and tend to be smooth or round. Fibroadenomas, which are benign tumors made up of glandular and connective breast tissue, are usually smooth and firm or rubbery to the touch. Both of these conditions tend to affect younger women; fibroadenomas are most common in women in their 20s and 30s, and cysts are most common in women under 40.

Despite these common descriptions, it is impossible to tell by touch whether a lump is cancer.

“The key point is that a woman should seek medical attention for any concerning lumps in her breasts,” says Harold Burstein, MD, PhD, a breast oncologist with the Susan F. Smith Center for Women’s Cancers at Dana-Farber. “Simple imaging techniques such as a mammogram or breast ultrasound can usually provide reassurance that the breast lump is benign, and if necessary, a breast MRI or biopsy can be used to evaluate whether the lump is cancerous.”

  1. I am 43 with known cysts and a known right breast firboadenoma. I had a mammogram last week which found a new solid oval circumscribed mass just adjacent to my known fibroadenoma (already biopsied with a marker placed) . The radiologist would not tell me mush except for he thought I should have it biopsied and a marker placed. The US tech stated to her it had the appearance of a fibro, but she could not be 100% for sure. I am now scheduled tomorrow with a breast surgeon for a consult and an us guided biopsy. What are the chances that this is another fibroadenoma? Im and so stressed waiting to find out.

  2. Hi, im sean and Im 21. I actually noticed something hard, round and painless thingy on my right breast probably more than 5years from now. Theres nothing wrong happening to me externally but im worried to death that it might be cancerous its just that the effect is inside my body. But i was thinking that if nothings happening to me for the past 5years, maybe this is benign. But im still scared because my grandma had breast cancer. I already searched a lot on how to distinguish benign from malignant cyst but still, I could hardly understand it. Omg. Can you please help me? Im scared to go to a doctor and then tells me that I have a cancer 😭 i just want to know if a cyst is cancerous, how long will it take for the effect on your body to occur or be visible? Thanks

      • Thank you for the answer. But i would like to know cos Im really curious about the lenght of time that a lump on the breast will have an effect on the body especially if it’s cancerous? Because in my case, its almost 5 years but i dont feel anything and any changes regarding my health. So i was like assuming it’s benign. Hopefully.

  3. Hi
    I’m just a 11th grade students and I’ve been experiencing a pain in the side of my left breast near my armpit. It doesn’t swell or redden but it is quite painful when I touch it. There is a lump but it feels just like a tissue not hard. I’m very worried is it an early sign of breast cancer? The pain will go away but eventually the pain will return. I tried to ignore it at first but it really bothers me.

    Hoping for your reply

  4. My right breast is somewhat different than my left breast, I have more tissue on the right side of my breast it is not even at all with the other breast I can tell the difference when my arm is down, I have felt a small size pebble on my right side close to my breast, it hurts sometimes I’ve felt pain in my right area around the pebble size. I’ve had told my doctor but she said it’s fat tissue. But would fat tissue hurt at time?

  6. Im an 18 year old girl and a few weeks ago I noticed a large, moveable lump in my breast. It recently got larger so I went to the doctor and she found a second lump, just the same, but smaller. I don’t have any other symptoms. She told me not to worry but my grandmother died of breast cancer so i am terrified. Is it possible i have breast cancer?

  8. Dear Dana-Farber

    I have been to my doctor 2 weeks ago concerning a large, hard lump located right behind my nipple.
    He then referred me to a private hospital where they did an ultrasound and suggested I go for a Tru-Core Breast Nodule Biopsy.
    However, it’s only scheduled to happen next week Thursday (20 October 2016).
    In the time that I’ve been waiting for this exam, my nipple is now completely inverted, the swelling is almost double the size of my other breast, and there is now a redness around my nipple where the lump is. It is extremely painful.

    Should I become concerned about this being cancerous?

    It was not painful in the beginning, neither was it swollen, and the lump was fixed in its place. I was able to move it around and my doctor diagnosed it with being a fibroadenoma, however still sending me for an ultrasound to be sure.

  10. I’m 14 and I found that I had a small, hard lump in my breast. It is not painful but I’m scared because my great grandma had breast cancer she is still alive but any who my period is late and I’m worrying I had this lump for at least 2 weeks.

  11. Dear Grace:

    Even though many breast lumps are not cancer, it’s certainly understandable that you would be a little scared. We can’t give out specific clinical advice over the blog, so we can’t say whether waiting til the first of the year is advised or not. That’s something you should definitely speak to your doctor about.

  12. Hi, I was doing a routine, almost out of habit self exam when I detected a small, hard, seems to be fixed in place pebble type of lump that has never been there. I know, I know, and I WILL call my Dr., of course. It’s Sunday, so it won’t be today.
    I guess my question is it possible it isn’t cancer? I’m understandably a little scared.
    IF I can live with the fear and uncertainty for that long, will waiting til after the 1st of the year hurt the situation that badly?
    I know early detection is key, I get that, however I have really awful insurance right now, but I have the opportunity each year to change it, starting each Jan. 1st.
    It’s only a couple of months, I’m scared to do the wrong thing, both health and financial-wise.

  13. Dear Zeh,

    We’re sorry to hear of your breast pain. We recommend you see your doctor about your pain, and he or she can advise you on any tests that may help determine what’s causing it.
