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
