I had a high blood pressure of 180, and my doctor had found out that there has been a 3 inch tumor on my lungs and my kidney, and recently I had peed a super less blood, but my doctor said that it would not be dangerous but had to check up again whether the tumor is grown or not after 6 months time. Perhaps, I'm afraid it would be a cancer, but based on my research, the most common tumor which can be a cancer is most likely about 7 inch or lesser and the tumor in mine is 3 inch, can this be a signs of cancer? Please would you help! I'm super worry!
