Can lung cancer patients eat watermelon?
Generally speaking, lung cancer patients can eat watermelon, but it should be consumed in moderation. Detailed analysis is as follows:

Watermelon is rich in various vitamins, such as vitamin C and B-complex vitamins, and also contains minerals like potassium. It can provide lung cancer patients with essential nutrients to help maintain normal physiological functions. Patients may lose significant body fluids due to the disease itself or treatment side effects, such as fever and sweating. Watermelon has a high water content, which can help replenish fluids, promote urination, reduce body edema, and aid in the elimination of metabolic waste.
Watermelon's sweet taste and juicy texture can stimulate the appetite of lung cancer patients who may suffer from appetite loss, encouraging them to eat more and obtain sufficient energy. However, it should be eaten in moderation to avoid discomfort such as abdominal pain or diarrhea caused by overconsumption.
If the patient also has diabetes, watermelon intake must be strictly controlled, as watermelon has a relatively high sugar content. Excessive consumption may cause blood sugar fluctuations, which are detrimental to disease management. Lung cancer patients should maintain a balanced diet and consume more foods rich in protein, vitamins, and minerals to enhance immunity and improve treatment outcomes. If there are any concerns or discomfort, patients should seek timely medical advice from a qualified physician.
