Melanoma is one of the malignant tumors, and if one contracts this disease, it is important to treat melanoma promptly as symptoms are not very pronounced in the early stages. In advanced stages, symptoms such as nausea and vomiting may occur, possibly due to irritation of the stomach. Surgery, chemotherapy, and radiotherapy can all have side effects. It is also possible that the melanoma has metastasized, causing a feeling of vomiting. It is recommended that patients take antiemetic medication to treat this, and in terms of diet, eat foods that are beneficial for the spleen and stomach, such as coix seed, yam, millet, red dates, and black fungus, all of which can help alleviate discomfort in the gastrointestinal tract.
