Male Breast Cancer: Warning Signs Men Should Not Ignore
By Dr. Gajendra Kumar Himanshu
Male breast cancer is a rare cancer that develops in the breast tissue of men. The most common warning sign is a new lump or thick area in or near the nipple. Other signs can include nipple discharge, an inverted nipple, skin changes, or swelling under the arm. Although most breast lumps in men are not cancer, any new or unusual breast change should be checked by a doctor.
Many men do not think breast cancer can affect them, so they may ignore a lump or nipple change. This can delay diagnosis.
In this blog, we will explain the warning signs of male breast cancer, its risk factors, how it is diagnosed, treatment options, and when a man should see a doctor.
What Is Male Breast Cancer?
Male breast cancer develops when abnormal cells in the breast tissue start growing out of control. Men have a small amount of breast tissue, including milk ducts, where most male breast cancers begin. Breast cancer is much less common in men than in women, but it can happen at different ages.
Most male breast cancers are ductal cancers, meaning they begin in the milk ducts. Because men have less breast tissue, a tumour may reach the nipple, skin or nearby tissues more easily. This is one reason why noticing changes early is important.

Warning Signs of Male Breast Cancer
The most common symptom is a lump in the breast, often under or near the nipple. It is commonly firm and painless, but a cancerous lump does not always feel the same in every person.
Other changes that should not be ignored include:
- A lump or thickening in the breast or underarm
- Nipple turning inward or changing direction
- Fluid or blood coming from the nipple
- Red, scaly, or swollen skin around the nipple
- Dimpling or puckering of the breast skin
- An open sore on the breast or nipple
- Swollen lymph nodes under the arm or near the collarbone
These signs do not automatically mean cancer. Conditions such as gynecomastia can also cause breast enlargement or a lump in men. However, a doctor should check any new or unusual change rather than assuming it is harmless.
Why Do Men Get Breast Cancer?
Male breast cancer can happen for different reasons. Some men have risk factors that increase their chance, while others develop the disease without a clear reason.
Important risk factors include:
- Older age
- A family history of breast cancer
- Inherited gene changes such as BRCA1 or BRCA2
- Previous radiation treatment to the chest
- Klinefelter syndrome
- Certain testicular conditions
- Liver disease that affects hormone levels
- Obesity
Having a risk factor does not mean that a man will definitely develop breast cancer. Similarly, some men diagnosed with breast cancer may not have any known risk factor.

When Should a Man See a Doctor?
A man should speak with a doctor if he notices a new lump, nipple discharge, nipple changes, skin changes or swelling around the breast or underarm.
Do not wait for pain before getting checked. Male breast cancer can be painless, particularly in its early stages. Early medical evaluation can help find the cause of the change and, if cancer is present, start treatment sooner.
Remember that most breast changes are not cancer. The purpose of getting checked is to find out what is actually causing the change.
How Is Male Breast Cancer Diagnosed?
Doctors usually start with a physical examination and questions about symptoms, personal health, and family history. If a breast change looks unusual, imaging tests may be recommended.
Test | Why it may be used |
|---|---|
Physical breast examination | Checks for lumps and other changes |
Mammogram | Provides detailed images of breast tissue |
Ultrasound | Helps examine a lump or abnormal area |
Core biopsy | Removes a small tissue sample to check for cancer |
Biomarker tests | Check hormone receptors and HER2 to help guide treatment |
CT, PET or bone scan | May be used to check whether cancer has spread |
A biopsy is usually needed to confirm whether a suspicious breast change is cancer. Doctors may also test the cancer cells for estrogen receptors, progesterone receptors and HER2 because these results can help guide treatment.
How Is Male Breast Cancer Treated?
Treatment depends on the type and stage of cancer, along with hormone receptor and HER2 results and the person's overall health.
Treatment may include:
- Surgery
- Radiation therapy
- Hormone therapy
- Chemotherapy
- Targeted therapy in selected cases
Surgery is commonly used for early male breast cancer. Because men have less breast tissue, mastectomy is more common than breast-conserving surgery, although the best approach depends on the individual tumour.
Hormone therapy is also important for many men because most male breast cancers are hormone receptor positive. Other treatments may be added depending on the cancer's features and whether it has spread.

Can Male Breast Cancer Be Treated Successfully?
Yes. The outlook for male breast cancer depends strongly on the stage at diagnosis and other features of the cancer. Cancer that is found while it is still limited to the breast generally has a better outlook than cancer that has spread to distant organs.
This is why men should not ignore breast lumps or nipple changes. Getting an unusual change checked does not mean you have cancer, but it can help make sure that a serious condition is not missed.

Male breast cancer is rare, but it is real. A lump, nipple discharge, inverted nipple, or unusual skin change should not be ignored simply because you are a man. Early evaluation can help doctors identify the cause and begin the right treatment when needed.
At Oncare Cancer Hospital, patients can discuss unusual breast changes, diagnostic tests, and treatment options with a cancer care team. If you have noticed a new breast lump or other warning sign, consult a doctor and get it evaluated rather than waiting for it to disappear on its own.
