Brief Answer:
Best to diagnose it, if harmless can leave it

Detailed Answer:
Hello ma'am and welcome.

Thank you for writing to us.

In my opinion, I am assuming this is not a sub-areolar abscess or a clogged XXXXXXX gland as you are not experiencing any pain, and sounds more like a bump ma'am (only assuming because I cannot visualise it). I would suspect breast fibrosis to be the more likely cause as it can be related to your age, because there are many hormonal changes that take place in a woman's body during that age. But of course, this will have to be confirmed.

I would like to know if you have any other symptoms like nipple discharge, swollen breasts, poor nipple health, condition of the skin around it, etc. Please write back to me with this information ma'am, it would greatly help me. If you are comfortable, you could also upload a picture of the affected region to our discussion, but if you are not, do not worry, just meet a doctor who you are comfortable with, so he/she can physically examine it.

I would also like to add that there are many other causes that could also cause a presentation similar to yours ma'am, and because of this I would be much more comfortable if you would schedule a general check up with your doctor. Please also discuss other details like the medications you are on or were on, your menstrual cycle, hormone levels will have to be checked, and so on.

Some of the causes include:
-Benign tumors
-Paget's disease of the nipple
-Cancer (rare)

So, in conclusion I would like to say that we need to attend to any change or abnormality in the body, to first make sure all is well, and if god forbid it is not, find the best way to treat it and ensure good health. So please do not just let this be, and schedule an appointment with your doctor.

In the meantime, you could initiate the application of warm compresses to the region several times a day, and also have a sits bath with epsom salt at least twice a day. If at all these are simple clogged XXXXXXX glands, then this should help.

I hope you find my response both helpful and informative ma'am. Please feel free to write back to me for any further clarifications, I would be more than happy to help you.

Best wishes.
