Cancer symptoms can vary depending on the type and stage of the disease, but some warning signs are common across many cancers. These include unexplained weight loss, ongoing fatigue, persistent pain, unusual lumps, changes in the skin, or a cough that does not go away. Having one of these symptoms does not always mean you have cancer, but it is important not to ignore changes that last for several weeks. If you notice persistent symptoms, visiting a trusted oncology hospital in Chennai can help you get an accurate diagnosis, timely treatment, and expert guidance for better health outcomes.
