Chest issues


Hello, Doctor: During puberty, when I experienced breast development, I happened to see a public service announcement on television stating that to check for breast cancer, one should feel under the nipple for a hard lump and perform circular massages three times to the left and three times to the right, which could reduce the risk of developing breast cancer.
At that time, I didn't know that boys could also experience breast development; I just felt pain in my chest.
After watching the announcement, I felt under my nipple and discovered a round hard lump, which scared me into thinking I had breast cancer.
So, I started massaging in circles (even though it was painful at the time, I endured the pain to avoid getting breast cancer).
Later, I learned that it is normal for boys to experience breast development and chest pain during puberty, but by then it was too late.
Now, my left breast is normal and swollen due to the development, but my right breast is completely flat (it was the right breast that developed during the announcement), with only the nipple visible on the skin.
I would like to ask the doctor if, at my current age, there is still a possibility for the right breast to develop again since it didn't develop successfully, or will I have to live with one breast being swollen and the other flat for the rest of my life? I apologize for the lengthy explanation, and I appreciate your patience in reading it.

Males do not experience breast engorgement, but they can experience nipple pain, which may sometimes be accompanied by swelling.
During puberty, some boys may experience nipple pain, typically unilateral, though bilateral cases can occur as well.
Similar conditions can also arise in older age, often associated with age and liver function abnormalities.
There are also some unexplained cases of adults experiencing similar symptoms, which may be related to smoking.
Overall, this condition is not serious and should not be a cause for excessive concern.

Understanding breast changes in males can be a complex topic, especially when considering the physiological and psychological aspects involved. Your concerns about breast development, pain, and the fear of breast cancer are valid and shared by many men who experience similar changes during puberty and beyond.

Firstly, it’s important to clarify that breast tissue in males can undergo changes due to hormonal fluctuations, particularly during puberty. During this time, some boys may experience gynecomastia, which is the enlargement of breast tissue due to an imbalance between estrogen and testosterone levels. This condition can lead to the development of lumps or tenderness in the breast area, often causing anxiety about potential malignancies such as breast cancer. However, it’s crucial to understand that male breast cancer is significantly rarer than in females, and the presence of breast tissue changes does not automatically indicate cancer.

In your case, you mentioned experiencing breast pain and noticing a lump during puberty, which is not uncommon. The lump you felt could have been a result of normal breast tissue development or gynecomastia. The fact that you have one breast that appears fuller than the other is also typical, as asymmetry in breast size is common in both males and females.
Regarding your question about whether your right breast could still develop further at the age of 28, it is unlikely that significant changes will occur at this stage in life. Most breast development occurs during puberty, and while some changes can happen later due to weight fluctuations, hormonal changes, or certain medications, the dramatic growth associated with puberty is generally not repeated.
If you are concerned about the asymmetry or any discomfort, it would be wise to consult with a healthcare professional. They can perform a physical examination and, if necessary, imaging studies to rule out any underlying issues. It’s also essential to monitor any changes in your breast tissue, such as new lumps, changes in size or shape, or any unusual pain or discharge, and report these to your doctor.

In terms of self-examination, while it’s good to be aware of your body, excessive manipulation of breast tissue can sometimes lead to unnecessary discomfort or anxiety. Instead, focus on being aware of any significant changes and discussing them with a healthcare provider.

Lastly, it’s important to address the psychological impact of these changes. Many men feel embarrassed or anxious about breast development, especially in a society that often stigmatizes male breast tissue. Support groups or counseling can be beneficial for those struggling with body image issues related to gynecomastia or other breast changes.

In summary, while breast changes in males can be concerning, they are often normal physiological responses. If you have persistent concerns about your breast health or notice any significant changes, seeking medical advice is the best course of action. Remember, you are not alone in this experience, and there are resources available to help you navigate these changes.
