good day doc! i am wondering whats on my butt cheek near near the cleavage of my butt  i wonder if its a node or a mass cyst?? when i touch it i feel it is hard and round shape  about 1.5 to 2 inches in the diameter... my father died last year of having lymphoma...im afraid that this is one of the symptoms of lymphoma. thanks
Hi, This site is uncommon for lymphoma. Probably other diagnosis should be kept in mind first. Lymphoma generally evident by lymph node swelling. That particular site has no specific lymph node station. Anyway the duration, pain, relation with defalcation should also be mentioned. If it is a rapidly progressing mass then it will be better to go for a tissue diagnosis.
