- Cancer
- Risk Factors
- Having certain risk factors means you are at increased risk of developing the disease
- Smoking - linked to lung cancer as well as mouth, bowel, stomach and cervical cancer
- Obesity - linked to many different cancers - including bowel, liver and kidney cancer - 2nd biggest preventable cause of cancer after smoking
- UV Exposure - exposure to increased UV radiation from sun - risk of skin cancer - sunny climates and lots of time outside increases risk - use of sun beds increase risk too
- Viral Infection - infection with hepatitis B and C can increase risk of developing liver cancer - likelihood of becoming infected depends on lifestyle - spread through unprotected sex and sharing needles
- You can also inherit faulty genes that make you more susceptible to cancer - mutations in BRCA genes have been linked to increased likelihood of developing breast and ovarian cancer
- Types of Cancer
- Benign
- Tumour grows until there is no more room
- Stays in one place (usually within a membrane) rather than invading other parts of the body
- Not normally dangerous and isn't cancerous
- Malignant
- Grows and spreads to neighbouring healthy tissues
- Cells can break off and spread to other parts of the body -travel by bloodstream
- Invade healthy tissues and form secondary tumours
- Dangerous and fatal - cancerous
- Uncontrolled growth and division is a result of changes that occur to the cells - results in formation of tumour (mass of cells)
- Survival rates have increased due to medical advances - improved treatment, early diagnosis and increased screening
- Benign
