Cancer

Cancer is a leading cause of death group worldwide and accounted for 7.4 million deaths (around 13% of all deaths) in 2004. The main types of cancer are:
                 Lung (1.3 million deaths/year)
                 Stomach (803,000 deaths)
                 Colorectal (639,000 deaths)
                 Liver (610,000 deaths)
                 Breast (519,000 deaths)

Risk factors for Cancers
                 Tobacco use
                 Alcohol use
                 Dietary factors, including insufficient fruit and vegetable intake
                 Overweight and obesity
                 Physical inactivity
 and some types of human papilloma virus (HPV)

How to fi ght cancer
Prevention
More than 30% of cancers are caused by several leading behavioural and environmental risks that are potentially modifiable. Tobacco use is the single largest preventable cause of cancer in the world today. It is responsible for up to 1.5 million cancer deaths a year.

Key strategies:

- Tobacco control by implementing the WHO Framework Convention on Tobacco Control (see the WHO MPOWER package, a set of six key tobacco control measures);
-Promotion of healthy diet and physical activity (see the WHO Global Strategy on Diet and Physical Activity for a comprehensive set of policy recommendations);
-Preventing harmful use of alcohol by means of national alcohol policies aimed at reducing overall level of alcohol consumption;
-Reduce exposure and promote protection against infectious agents associated with cancer, including vaccination against Hepatitis B Virus and Human Papilloma Virus
-Reduce exposure and promote protective actions, to carcinogens in the environment and workplace,

                o          PAP test  for cervical cancer in middle-, and high income settings
                o          Mammography screening for breast cancer in high-income settings

Treatment
Treatment  is the series of interventions, including psychosocial support, surgery, radiotherapy, chemotherapy that is aimed at curing the disease or prolonging life considerably while improving the patients quality of life.
Key strategies: Treatment of  early detectable cancers: Some of the most common cancer types, such as breast cancer, cervical cancer, oral cancer and colorectal cancer have higher cure rates when detected early and treated according to best practice. Treatment of other cancers with potential for cure: . Some cancer types, even though disseminated, such as leukemias and lymphomas in children, and testicular seminoma, have high cure rates if appropriate treatment is provided.

Palliative Care
Palliative care is an urgent humanitarian need worldwide for people (adults and children) with cancer and other chronic fatal diseases. It is particularly needed in places where a high proportion of patients present in advanced stages and there is little chance of cure.
Relief from physical, psychosocial and spiritual problems can be achieved in over 90% of advanced cancer patients through palliative care.
Key strategies: Effective public health  strategies, comprising community, home-based care approaches are essential to provide pain relief and palliative care for patients and their families in low resource settings.
Improved access to oral morphine is mandatory for the treatment of moderate to severe cancer pain, suffered by over 80% of cancer patients in terminal phase. majority of patients are diagnosed in very late stages.
-Screening programmes for frequent cancer types that have a screening test that is cost-effective, affordable,  acceptable and accessible to the majority of the population at risk. Examples of screening methods:
o    visual inspection with acetic acid for cervical cancer in low resource settings;
