World Cancer Report

Released by IARC (International agency for research on cancer), a part of World health organization (WHO), World cancer report is a concise informative manual that have a clear description about global cancer statistics, causes, main types, early diagnosis and effective treatment. The director-general of WHO, Dr. Gro Brundtland states 'The report provides a basis for public health action and assists us in our goal to reduce the morbidity and mortality from cancer, and to improve the quality of life of cancer patients and their families, everywhere in the world.'

Major findings

The report has published these results:

Tobacco- the most preventable cancer cause

In the last century, more than 100 million died all over the world from the diseases that are associated with tobacco consumption. These are:

* Cancer

* Chronic lung disease

* Stroke

* Cardiovascular disease

The regrettable fact is, the patients could have been prevented from such medical problem had they not used any tobacco. Lung cancer risk is 20 to 30 times more in smokers than non-smoking persons. About 90 % of all lung cancers are tobacco associated, in both men as well as women. In bladder and renal pelvis cancer, 50 per cent or more are due to smoking. For the cancer of mouth, larynx, pharynx, esophagus the RR is greater than six. For pancreatic carcinomas it is three to four. Stomach, liver, kidney, naval cavity, sinuses, esophagus (adenocarcinoma) cancer and myeloid leukemia two-three RR has been identified by the researchers. Even passive smoking can lead to lung cancer, and increases the risk by almost 20 percent. However, tobacco is not yet known to have any role in the incidence of prostate, breast and endometrial cancer of the uterine, since there is no evidence of this at present.

Infection is a great risk factor

Approximately 23 per cent of malignant diseases in developing countries occur due to the infections. These can cause:

* Liver Cancer (Hepatitis B and C virus)

* Cervical cancer (HPV, human papillomaviruses, HPV)

* Stomach cancer(Helicobacter pylori)

Whereas, in developing world, only 8 percent of all such malignancies are attributed to infectious agents.

Vaccines for prevention: These could be highly effective in treating cancers caused by infections. HBV vaccination is successfully being used to prevent liver cancer in countries where incidences are high and most probably HPV (human papillomavirus) vaccination will also work within three to five years.

Diet is curing

Stomach cancer can be prevented from occurring if the intake of salt-free preserved meat and fish is avoided. In many countries of Europe, such as Switzerland and nearby places, mortality rate has decreased by 60 percent within one generation. It is hoped, in the coming 30 years, stomach cancer can become a rare type in many parts of the world. In many other countries like Japan, Korea, Brazil, and Portugal, where salted food is excessively eaten, the incidence of gastric cancer are high but fallen considerably.

According to studies, taking plenty of fresh fruits and vegetables on a regular basis can prevent or help in cancer recovery.

Strategies for cancer control

The aim of these procedures and techniques is to reduce the occurrence as well as the cancer death rate that is the ultimate consequence of the fatal disease. Post disease life improvement for the patient is also included. Treating the disorder is not enough, the care and health condition afterwards throughout one's life is considered also that is equally important. Early diagnosis is really essential to avoid further complications and off course the death of affected person.

The report has revealed information about all aspects of cancer including the statistics of incidence by each type all over the globe. Nutrition is a key factor, discussed in detail; various other facts are discovered in it.
