Seen 2 drs about a groin lump. both said it was a reactive node. how long will the swelling last? 3rd week now. still worrying about cancer.

Not worth worry: Unless your lymph node is growing in size and it gets bigger than 1-2 cm over the next 1,2 or 3 months, you have no reasons to worry about. There is no medical condition associated with a "reactive" lymph node. It is a vague and nonspecific term. So I would ignore it unless it changes in size which is not going to happen in 1,2 or 3 weeks time.

Sometimes as: long as several weeks to months, depending upon how long it takes to treat the underlying inflammatory or infectious problem. Cancerous lymph nodes have a peculiar induration and enlargement, so your doctors are relying upon their clinical experience when they tell you that it is not malignant.

Lymph node enlarged: In general lumps in the groin can be present and up to 1.5 or 2 cm in size. They are generally reactive but low grade lymphomas ( lymph node cancer ) can present like this. It is however a condition that we generally watch and don't jump into treatment. I 'd wait for another week , if the node is growing then I will recommend removing it as a a biopsy. for now your 2 doctors are correct .

Check the skin: Make sure to check your skin all along your leg, including your foot for anything that could be causing the reactive node. Also make sure to ask about the possibility of a hernia. If nothing, and your still worried, you could have it surgically removed and sent to a pathology lab to find out for sure. Hope this helps!
