Hi, thank for using HCM.
In your case, the only thing to do is to wait until the biopsy
is done. The groin is an area where lymph
nodes can enlarge for multiple reasons. Infectious disease is one of the more important causes of lymph nodes enlargement. So, you are a young woman. Old Age is risk factor to have cancer. You are young, so in your case is more probable to have a infectious or an autoinmune disease than cancer. But only biopsy could define this. So be patient.
