As an oncologist with extensive experience in cancer care, I can tell you that weight loss is a common symptom in many individuals with cancer. This can occur due to various reasons such as reduced appetite, increased metabolism, or the body's response to the disease. However, it's important to note that not everyone with cancer will experience weight loss, and weight loss alone is not a definitive indicator of cancer. Weight loss can be a symptom of many different health conditions, and it's crucial to consult with a healthcare professional for a proper diagnosis if you or someone you know is experiencing unexplained weight loss. It's also worth mentioning that while weight loss can be a side effect of cancer, it's not exclusive to cancer.

It is always best to seek medical advice for any concerning symptoms. read more >>
