2. Cancer Definition
• Cancer refers to a large number of diseases characterized by
the proliferation of abnormal cells irregularly, which have
the ability to penetrate and destroy normal body tissue.
• Cancer also has the potential to spread throughout the
body.
• Cancer is the second leading cause of death in the United
States.
3. The risk of cancer occurrence
• Calculated at the age of 75 years, the risk of any type of cancer is:
• 1 in 4 women and 1 out of every 3 men.
• The risk of common cancers
• - Prostate 1 out of every 9 men
• - Breast 1 out of every 11 women
• - Colorectal 1 out of every 28 people
• - Skin (melanoma) 1 out of every 31 people
• - Lung 1 out of every 42 people
4. Report on the Incidence of Cancer Cases in Saudi Arabia in 2010
• Between January 1 and December 31, 2010
• The total number of cancer cases reported to the Saudi Council of
cancer was 13706.
• The total cancer cases are more among women than men.

• 10230 case among Saudis
• 3265 among non-Saudis
• 211 of unknown nationality.
5. Report on the Incidence of Cancer Cases in Saudi Arabia, 2012

• Total number of cancer incident cases reported to the Saudi Cancer
Registry (SCR) was 14,846.
• Overall cancer cases were more among women than men;

• Total of 11,333 cases were reported among Saudis

10. Predisposing risk factors of cancer
• Age,
- most patients with cancer are aged 65 years or more, but the cancer
can occur at any age.
• Smoking,
- increases the risk of cancer in smokers several times higher than
non-smokers, and the risk increases the more the duration of smoking
increased or the amount of smoking in the day. Even passive smoking
increases the risk of cancer.
- tobacco use is the most important risk factor for cancer, and causes
about 20% of cancer deaths, and about 70% of lung cancer deaths.
11. • Drinking alcohol,
- leads to increased risk of cancers of the digestive tract.
• Excessive exposure to the sun or frequent sun burns,
- lead to an increased risk of skin cancers (melanoma).
• Obesity and non-healthy diet and physical inactivity,
- are major risk factor for cancer, and lead to an increased
risk of cancers of the colon.
• Unprotected and illegal sex
- lead to an increased risk of cancers of the genital system.
12. • Genetics,
- only have a small role; cancers occur due to genetics
especially cancers of the blood.
• Environment,
- may contain harmful chemicals that can increase the risk of
cancer. Chemicals such as asbestos and benzene, are also
associated with an increased risk of cancer.
13. • Some pathological conditions and biological factors,
• - Ulcerative colitis, predisposes to colon cancer.
• - Infection with the human papillomavirus HPV increases
cervical cancer.
• - EBV virus can be significantly increases the risk of
developing certain types of cancer.
• - Hepatitis B (HBV), and hepatitis C increase the risk of liver
cancer.
• - Infection with HIV dramatically increases the risk of skin
cancers and lymphoma.
14. • Ionizing radiation and non-ionizing radiation from mobile
phones .
• Some pollutants, food colorants and additives in the food
industry.
• Air pollution in cities, can increase the risk of some cancers.
15. How to reduce the burden of cancer?
• Effective education to disseminate the knowledge about
the predisposing factors of cancer, for early detection of
cancer, a timely intervention to prevent disease
progression, and management of patients with cancer.
- Many types of cancer have a high chance of cure if detected
early and treated adequately
• Modulate and avoid risk factors
- More than 30% of cancer deaths can be prevented by
modifying or avoiding key risk factors
16. Cancer Prevention Strategies
• Avoid the predisposing risk factors that increase cancer occurrence.
• Vaccination against human papilloma virus (HPV) and hepatitis B
(HBV)
• Occupational risk control.
• Avoid excessive exposure to sunlight by staying in the shade, wear
protective clothing or applying sunscreen.
• Reduce exposure to radiation (diagnostic imaging medical or
professional) ionizer.
• Exercise most days of the week, regular exercise for at least 30
minutes a day.
17. Early detection
• Can reduce cancer deaths if the case detected and treated
early.
• This can be done by early diagnosis through the following
- Detect the early signs and symptoms (for different types of
cancer, such as skin, cervical, breast and colorectal cancer,
bronchus and throat) in order to start the suitable
investigations for diagnosis and consequently apply the
required treatment at an early stage.
18. Periodic detection
• Periodic detection, aims to identify individuals with
disorders suggest a specific cancer or pre-cancerous stage,
and immediately referred for diagnosis, or when it is
possible for diagnosis and treatment.
• Periodic detection programs are particularly effective for
some types of cancer, acceptable and accessible to the
majority of the population at risk.
19. • Examples of detection programs are:
• HPV test for cervical cancer.
• PAP smear to investigate cervical cancer.
• mammography to detect breast cancer.
• Colonoscope for the detection of colorectal cancer
20. CANCER PREVENTION RECOMMENDATIONS
• 1- Be as lean as possible without becoming underweight.
• 2- Be physically active for at least 30 minutes every day.
Limit sedentary behavior.
• 3- Avoid sugary drinks. Limit consumption of energy-dense
foods.
• 4- Eat more of a variety of vegetables, fruits, whole grains
and legumes such as beans.
• 5- Limit consumption of red meats (such as beef, pork and
lamb) and avoid processed
21. • 6- Avoid alcoholic drinks.
• 7- Limit consumption of salty foods and foods processed
with salt (sodium).
• 8- Don't rely on supplements to protect against cancer.
• 9- NEW MOTHERS: Breastfeed babies exclusively for up to 6
months and then add other liquids and foods.
• 10- CANCER SURVIVORS: After treatment, follow the
recommendations for cancer prevention.
• And always remember — do not smoke or chew tobacco.
•
22.
23. Innovation
• Open a new clinic named : Periodic Disclosure Clinic
• Tasks:
- Application of accredited cancer preventive programs
- Application of accredited preventive programs of other
conditions
- Follow up of the results and outcomes of these programs
- Coordinate with other clinics and departments about the
detected diseases for the proper and timely management
