Good Day Dr Krueger, I am a bit concerned about my husband he had melanome cancer about 5 years ago. Had operation, mule removed and had chemo in the form of an injection he got 3 times a week for 18 months. He went for test SB100 and it was said he is fine last followed up a year ago. About 3 weeks ago he became aware of a lump at the side of his neck in the vicinity of the lower jaw. We live in a very small town and going to see the GP tomorrow but how can we make sure that the necessary test is done to make sure there is no gland or any other serious problem. His oncologist was in Pretoria but he is not registered as a oncology patient at the medical aid. Please give me an idea what is the next step to follow. Is a SB100 test reliable to be sure. In fact we told the GP this was the test done and according to that he did the test. Thanks I am a very worried wife and do appreciate your assistance. Rina Swart
