Hi, 3 weeks ago I was diagnosed with a tumour on my peritoneum, which is pushing on my right kidney causing me to be in a lot of pain. The tumour is about 5cm x 5cm x 7cm. Over the last two weeks I have had CT scans and it was diagnosed as Lymphoma. But last week after a biopsy of the tumour we were told by the consultant it's not Lymphoma but could be Kidney cancer, although it isn't in my right kidney. I have now been referred to a Urologist consultant who I'm seeing this week. I'm wondering if anybody else has a similar issue. I am a 57 year old male, and read it's very rare for males to get cancer in there peritoneum, as it's linked to ovarian cancer?
