关于肿瘤的英语作文高中

Here's a 250-word high school English essay about tumors:

Understanding Tumors

Tumors are abnormal masses of tissue that form when cells divide uncontrollably. They can be benign (non-cancerous) or malignant (cancerous). Benign tumors usually grow slowly and don't spread, while malignant tumors can invade nearby tissues and metastasize to other body parts.

The causes of tumors vary. Genetic factors, unhealthy lifestyles (like smoking), environmental pollution, and certain infections can all contribute. Early detection through regular check-ups is crucial, as treatments like surgery, chemotherapy, or radiation are more effective in initial stages.

Modern medicine has made significant progress in tumor treatment. Immunotherapy and targeted therapy are promising new approaches. Meanwhile, maintaining a balanced diet, exercising regularly, and avoiding carcinogens can help prevent tumors.

Though tumors remain a global health challenge, scientific advances and preventive measures give us hope. Public awareness about early symptoms and risk factors is essential in this ongoing battle.
