I had small lump in areola but I checked it many times so it now growed into a disk large lump so what now will it go? Does this mean my t. Is low?

Not necessarily. Go to see your doc and have further examination. If I am not mistaken, you are talking about a breast lump/breast enlargement correct- or gynecomastia. There are different causes of gynecomastia- from hormonal, medication, other disease-such as liver disease, tumor etc. If your doctor thinks that there is a lump there- a mammogram or sonogram of the breast as well as other blood tests can be done.
Areola. Number of modified sweat glands in areola. Suspect has gotten infected can happen spontaneously. May require surgical intervention. Not low testosterone sx.
