Three types of cancer that may disappear in the coming decades
According to experts from the World Health Organization, humanity has every chance of defeating several types of cancer in the coming decades. RIA Novosti understands which cancers are becoming a thing of the past and why.
WHO representative Melita Vujnovich said that humanity will not defeat cancer in ten years, but it will definitely cope with some of its species. And above all, world medicine is close to defeating cervical cancer, which today is considered the fourth most common among women. More than 570 thousand new cases are registered in the world annually, and 7.5 percent of deaths from malignant tumors are accounted for by this type of cancer.
At the same time, the disease itself has been well studied, and a safe and effective vaccine has been developed against its causative agent, the human papillomavirus (HPV). Several clinical trials and separate studies have shown: in women vaccinated with her at the age of 12-13, after ten years there is no precancerous or neoplastic pathology of the cervix. The same cannot be said about their non-immunized peers.
There are practically no side effects. Very rarely, minor neurological symptoms. So, headache – only four out of a hundred thousand vaccinated. Data on the more severe consequences of vaccination, which appeared in 2016, have not been confirmed.
Australians were the first to massively vaccinate teenage girls in 2007. In 2017, the number of precancerous pathologies and cervical cancer among women aged 18 to 24 years decreased by half, and the infection with the virus decreased almost 20 times – from 22.7 to 1.5 percent. At this rate, by 2066, cervical cancer will completely disappear from the Green Continent.
Australia’s example was followed by many countries – vaccination against HPV was included in the national immunization schedule of 98 countries. However, the vaccine is not sufficient, specify WHO. It is important to test adults for HPV and timely detect precancerous conditions and malignant tumors in women. First, the cancer, if diagnosed early, is curable. And secondly, screening and treatment of precancerous lesions are more financially profitable than combating advanced cancer.
Weapons of mass destruction
WHO experts believe that the victory over lung cancer is not far off. However, on condition of complete cessation of smoking.
According to the International Agency for Research on Cancer, lung cancer is the second most common. Men are especially affected: among them, 18 percent of deaths are from this.
Moreover, as calculated by WHO experts, 90 percent of these malignant tumors would not exist if people did not smoke. In Europe alone, nine out of ten deaths, including premature deaths, from cancer of the trachea, bronchi and lungs are due to tobacco use.
The fact is that cigarette smoke contains more than 60 carcinogens, and nicotine suppresses the immune system. No less dangerous are vapes and light cigarettes that are popular today (holes are made in their filter, supposedly helping to purify smoke from tar, nicotine and other carcinogens). The former often lead to the formation of malignant tumors, the latter cause one of the most aggressive forms of lung cancer – adenocarcinoma.
As noted in the WHO, we need government programs to quit smoking. It is necessary to raise taxes for cigarette manufacturers, ban smoking in public places.
In 2019, the Russian government approved the anti-tobacco concept of the Ministry of Health until 2035, which covers cigarettes, vapes and tobacco heating systems. It is assumed that in 15 years, no more than 21 percent of the adult population will smoke. In the meantime, they will enter the top ten most smoking countries – according to the medical journal of The the Lancet.
The main thing is to stop drinking
There is also every chance of coping with liver cancer. This requires a significant reduction in alcohol consumption.
As established by WHO experts, more than 740 thousand cases of cancer in 2020 are associated with alcohol. Almost 75 percent are for men. This is cancer not only of the liver (154 thousand), but also of the esophagus (189 thousand, the most common), oral cavity, colon.
Most often, alcohol-associated cancer was diagnosed in Mongolia – 9.8 percent of the total number of malignant neoplasms. And in countries where alcohol is traditionally banned, for example in Kuwait , there were practically no such diseases. Russia’s indicator is six percent.
Another cause of liver cancer is viral hepatitis. Hepatitis B virus is found in about 70 percent of patients with this diagnosis. However, an effective and safe vaccine is available for this infection. In Russia, it is included in the National Vaccination Schedule and is absolutely free. According to experts, vaccination, together with a reduction in alcohol consumption and timely screenings, will significantly reduce the incidence of liver cancer. And in the long term it will even cope with it.
