Hi, thanks for writing to HCM and sharing your recent health concerns! Well, this is gynecomastia only and nothing to worry about this; just relax! Gynecomastia is very common at your age and it is described as partial feminine character/development of male breast tissues under hormonal influences especially in over-weight males. Sometimes it may contain small cysts within it and that may bleed when injured/crushed/squeezed... I would further suggest you to go for an FNAC /biopsy and ultrasound of the lump for confirmation and to relieve your concerns and you must see a surgeon for a proper direct and close clinical examination also! Hope this answers your question. If you have additional questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
