Unintentional weight loss
Another worrying sign is that in the early stages of cancer, you might experience a loss of appetite and unexplained weight loss. If there’s no diet changing or an active gym membership in your routine, and you are still losing weight, you should ask yourself if everything is alright.
Advanced cancer is linked to inflammation and the release of cytokines(proteins that regulate inflammation).
These too can produce a loss of appetite and weight loss. Tumors that are located high in the chest can also push on the esophagus(also known as food pipe), making it way more difficult to swallow or eat.
