Some common signs that may suggest cancer include unexplained weight loss, persistent tiredness, unusual lumps or swellings, changes in the skin such as new moles or sores that do not heal, persistent pain, or changes in bowel or bladder habits. Other warning signs may include persistent coughing, difficulty swallowing, or unusual bleeding. These symptoms do not always mean cancer, but if they last more than a few weeks, it is important to see a doctor for evaluation.

You should drink plenty of fluids, including oral rehydration solutions, to prevent dehydration. Eat small, bland meals like rice, toast, or bananas as your appetite allows. Rest as much as possible and avoid fatty or spicy foods. If symptoms persist for more than two days, or if you notice blood in your stools, please see a doctor promptly.

Megstrol 160 mg tablet (Megestrol) can sometimes be used to help increase appetite and weight in adults, but it should only be given under a doctor?s supervision. It may cause side effects such as fluid retention, blood clots, or changes in blood sugar. Your father should be evaluated by a doctor first to determine the cause of his weight loss and whether Megestrol is appropriate for him.

You should rest and drink plenty of fluids to prevent dehydration. Take over-the-counter paracetamol or ibuprofen as needed to reduce fever and ease body pain. Eat light, easily digestible meals when you feel able. If your fever persists beyond 3 days, becomes very high, or you develop new symptoms such as difficulty breathing or a rash, please see a doctor promptly.
