The number of oncological diseases in the world is increasing every year. And despite notable successes in the treatment of cancerous tumors, especially at the initial stages of their development, doctors are not yet able to determine exactly what is the cause of the malignancy.
One of the risk factors, as researchers have proven, is tobacco addiction. It is smokers who are significantly more likely to develop lung and nasopharyngeal cancer than people who do not depend on tobacco. However, a recent study by doctors from the United States has shown that the human papillomavirus is an even more significant factor in the development of upper respiratory tract cancer. The study has been conducted for more than twenty years in Los Angeles, Iowa, and Hawaii. If in the 1980s the number of patients who had both the human papillomavirus and malignant neoplasms was just over 16%, then in the 2000s the percentage of coincidences exceeded 72%.

The human papillomavirus is especially dangerous for men from the perspective of the development of malignant tumors. The main danger of the virus for women (increased risk of cervical cancer) has been proven for a relatively long time, and today timely examination and preventive measures make it possible to eliminate the disease at an early stage. As for men, the increased risk of cancer, according to the scientists who conducted the study, is an increase in the number of adherents of oral sex, during which the infection from the woman's body passes into the most vulnerable area of the genitals for men. The researchers noted that malignant tumors on the background of HPV are especially characteristic of people who started sexual activity early and often changed partners.

Women's memory is better

This is the opinion of a team of neurologists and psychologists from the UK, who have studied the potential in the field of memorization in men and women. The conducted research has shown that in terms of memorizing information, the female brain is arranged more rationally.

The study involved about 4,500 volunteers aged 45 to 90 years. All of them have passed a series of tests to determine the quality of memory. It turned out that women have significantly better memory on average, and this did not depend on age.

Experts believe that it's all about the original organization of human brain activity. Since this organization differs significantly between men and women, this means, first of all, that treatment for disorders of these functions should be different. Accordingly, the treatment of, for example, age-related memory disorders and dementia (dementia) should also be extremely thoughtful, determined not only by the age and general health indicators of the patient, but also by gender differences. In addition, scientists believe that the results of the study will make it possible to more accurately diagnose the development of age-related brain disorders in the early stages.
