Lump

Patient: Three months ago I found a lump in my neck. I saw a doctor who said he was 95% sure it was a swollen lymph node but ordered a ton of test anyway. After realizing the cost of the tests ordered I did not feel comfortable spending the money based on a 5% chance. Well the lump has not gone away and I am wondering if it is possible it is still a swollen lymp node or should I proceed with the testing?
