英文小作文：

I had a friend who experienced frequent hemoptysis after undergoing surgery for lung cancer. She was advised to rest at home and avoid any strenuous activities, but the condition persisted for several weeks. She was finally referred to a specialist who diagnosed her with infection-induced hemoptysis. After receiving treatment, her condition improved significantly and she was able to resume her normal activities.

This experience taught me that hemoptysis is a serious condition that requires immediate medical attention. It can be caused by various factors, including lung cancer, infection, allergic reactions, and respiratory infections. If you experience hemoptysis, it is essential to seek medical attention promptly to ensure proper diagnosis and treatment.
