Brief Answer: Hi XXXXXXX and welcome to XXXXXXX Detailed Answer: Thanks for the query. Considering your description,there is no need to be worried at all. You are to young too be concerned about such serious diagnoses. Cancers may develop in any man and in any age,but being hypohondriac will just have bad effect on your quality of life. Generalized lymph node swelling due to malignant disease is seen only in terminal malignant patients or in some type of lymphomas. So if there is cancer which caused metastases into lymph node,you would already have clear symptoms of primary cancer since such lymph node invovement is late sign of cancers. Do you have any other difficulties( pelvic pain,lung symptoms, stomach pain, weight loss)? Your lump near spine sounds like being subcutaneous lesion. Most commonly this is lipoma,but it can be fibroma,cyst, ateroma or any other benign tumor. There are also some tumors made of muscle cells found in this area. It doesnt actually matter what type of lesion it is exactly since the management and prognosis is the same. These lumps usually grow slowly and it isnt symptomatic unless it become inflamamted or extremely enlarged. The possiblity of malignant tumor in this area is negligible. Such subcutaneous cancers such as sarcomas or myosarcomas are extremely rare and there would be rapid grow with signs of inflammation around it and intensive pain. People can normally feel lymph nodes in neck,armpits and inguinal region.Some of these are enlarged our whole life and some become larger due to infections. It is true that sometimes it becomes enlarged due to cancer,but of course this is the last thing to think of and some other signs are necessary to make doctors suspicious about it. So I dont see a reason for some specific diagnostic tests,but for your satisfaction you can do ultrasound and needle biopsy if you are not afraid of needle. I am sure it will show normal cells in any lumps or lymph node that you can feel, but some people want proof that this is not malignant so needle biopsy is performed.I wouldnt do it in your case. If this would still bother you then there is always an option of surgical removal under local anasthesia. I am sure that this lump near spine cant related to your back pain. It should compress medula spinalis or surrounding nerves but it is not possible unless there is huge malignant process. Lipomas or fibromas rarely cause some significant pain,but sometimes it can irritate some small skin nerves. . In your case it sounds to me more like neuromuscular pain due to fybromialgia or lumbago. All you need is a good physical therapy. Of course, stress and concerns can only make thing worse and I am sure that pain will subside when you relax physically and mentally. Exercise will always help. Try to go swimming,running, do stretching exercises or yoga. The only test I would advice is basic blood work where blood cancers can be ruled out. everything else isnt necessary at this point. Wish you good health. I ll be glad to answer any further question. Regards
