A person with Hodgkin's disease has abnormal cells growing in their lymph nodes. The cells grow faster than other cells, destroy 'good' cells and can spread to other parts of the body. The true cause of Hodgkin's is not known.  

Who is at risk?

• People most at risk are those whose immune systems are compromised, either through transplants, HIV infection or other illnesses
• Hodgkin's is not fussy about race, but occurs more often in men than women
• It often strikes young people between the ages of 15 and 30
• The risk factors that relate to other cancers, such as diet, smoking, unprotected sun or pesticide exposure, are not related to Hodgkin's disease 

What are the symptoms?

It is a neurological condition, which affects movements such as walking, talking, writing and swallowing. The cause of Parkinson's is not known. The symptoms are, however, caused by loss of the chemical messenger Dopamine from the brain cells which control movements like walking, talking, swallowing and facial expression.  

What are the symptoms?

• Trembling
• Stooped posture
• Muscular stiffness
• Short, shuffling steps
• Soft, rapid speech
• Poor balance
• Poor handwriting
• Slowness
• Depression
• Increased perspiration and oiliness of the skin 

What more is known about Parkinson's?

A stroke occurs when a blood vessel supplying oxygen and nutrients to the brain either burst or becomes clogged with a blood clot. As a result, some of the brain doesn't receive the blood it needs and brain cells start to die. Prompt treatment can prevent it from being fatal or disabling.

How can I reduce the chances of getting one?

• Check your blood pressure regularly. If it's high, you're at risk
• If you're on medication for high blood pressure, don't go off it without your doctor's consent
• Check your cholesterol levels. Cholesterol, a waxy substance that builds up in the blood narrowing blood vessels, increases the chances of a stroke
• Quit smoking: it makes your blood clot
