As an oncologist with years of experience in cancer research and patient care, I can tell you that the experience of cancer can vary greatly from one individual to another. While it's true that many types of cancer can cause pain, especially as they grow and potentially compress or erode into nerves or other structures, there are also instances where cancer may not cause severe pain or may even be painless initially. For some patients, the first signs of cancer might be a lump or unusual changes that don't necessarily come with pain. Additionally, certain types of cancer, such as some forms of leukemia or neuroblastoma, might not cause pain until they have advanced significantly. It's also possible for a slow-growing cancer to not cause pain at all, at least not in the early stages. However, it's important to note that the absence of pain does not mean that cancer is not present or serious. Regular check-ups and being aware of any changes in your body are crucial for early detection and treatment. read more >>
