Pg.no. 57 There are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms including:  a persistent cough  coughing up blood  persistent breathlessness  unexplained tiredness and weight loss  an ache or pain when breathing or coughing Treating lung cancer Treatment depends on the type of cancer, how far it's spread and how good your general health is. If the condition is diagnosed early and the cancerous cells are confined to a small area, surgery to remove the affected area of lung is usually recommended. If surgery is unsuitable due to your general health, radiotherapy to destroy the cancerous cells may be recommended instead. If the cancer has spread too far for surgery or radiotherapy to be effective, chemotherapy is usually used. 20. Malaria: Malaria is a serious tropical disease spread by mosquitoes. If it isn't diagnosed and treated promptly, it can be fatal. A single mosquito bite is all it takes for someone to become infected. Symptoms of malaria It's important to be aware of the symptoms of malaria if you're travelling to areas where there's a high risk of the disease. Symptoms include:  a high temperature (fever)  sweats and chills  headaches  vomiting  muscle pains  diarrhea Preventing malaria Many cases of malaria can be avoided. An easy way to remember is the ABCD approach to prevention:  Awareness of risk – find out whether you're at risk of getting malaria before travelling  Bite prevention – avoid mosquito bites by using insect repellent, covering your arms and legs, and using an insecticide-treated mosquito net
