What kind of people do netizens comment on being a Type C personality? Does Cancer Really Like Type C Personalities Best? Is it true that some people say “Cancer and blood type are also related”? Let’s see together
01
What is a Type C personality? Does cancer like this character the most?
Type C personality
The “C” is taken from the initials of “Cancer”, also known as “Cancer Character”. The characteristics of this type of personality are: hesitant, not good at expressing emotions, avoiding conflict, and excessive self-restraint.
We often hear the phrase “worrying becomes a disease”, so many people associate this C-type personality with cancer.

But in fact, this is a conceptual confusion, and the term “cancer character” is not scientific.
Long-term unresolved negative emotions may have an impact on health, but at present, there are no clear experimental results or data that can fully prove which personality type is associated with a higher incidence of cancer.
02
Is cancer related to blood type? In addition to “Cancer Personality”, there was also a previous term for “Cancer Blood Type”.
Similarly, there is no necessary link between cancer and blood type. At present, there is no research that can fully prove which blood type cancer prefers, and there is no scientific basis for the claim of “cancer blood type”.

There are many factors that cause cancer, and most studies do not comprehensively consider all the influencing factors. Therefore, such terms as “cancer personality”, “cancer blood type”, etc. have limitations.
03
What exactly is cancer related to?
Then some people have to ask, since cancer is not necessarily related to personality and blood type, what factors are related to cancer? In fact, the pathogenesis of cancer is complex and there are many causative factors. So far, cancer is still a difficult problem that the medical community is trying to overcome.
If the causative factors of cancer are generalized, they can be divided into the following categories:
(1) Genetic factors studies have confirmed that there are certain genetic factors in the pathogenesis of common malignant tumors such as breast cancer, kidney cancer, liver cancer, and gastric cancer. However, carrying a certain oncogene does not necessarily mean that you will get cancer, it just means that the carrier is more susceptible to cancer under the same other conditions.
(2) Age Factors Aging is an important factor in the occurrence of cancer. As we all know, the cells in our body are constantly dividing, replicating, producing new cells and eliminating old cells every day. However, with age, the body’s ability to generate new cells will gradually weaken, and the probability of “errors” in division and replication increases. When these “errors” are not corrected or cleared in time, they will inevitably “accumulate” There is a “out of control” scene, which leads to the occurrence of cancer. However, with the development of society, more and more studies have also confirmed that cancer is no longer the “patent” of the elderly, and cancer has gradually developed towards younger people.
(3) Life factors If cancer pathogenic factors are divided into congenital factors and acquired factors, then acquired factors account for more than half of cancers, and among acquired factors, cancers caused by poor eating habits and living habits can also account for more than half.

As we all know, alcoholism, smoking, staying up late, high-sugar and high-fat diets are all unhealthy habits. Up to now, quite a few studies have fully confirmed that these bad habits increase the risk of cancer. In addition to the above factors, there are also various factors such as the external environment (such as working in places with long-term ionizing radiation, carcinogens in the living environment, etc.), infectious factors (such as Helicobacter pylori, hepatitis B virus, human herpes virus, etc.) related to the occurrence of cancer.
04
Cancer is not contagious but the causative agent is contagious?
There are genetic factors in the occurrence of cancer, so many cancers with genetic predisposition are called “familial cancers”, but in fact “familial cancers” not only include these cancers with genetic predisposition, but also some are infected by “disease factors” “causing cancer. The “contagion” here does not refer to cancer. Cancer itself is not contagious, but the causative factor is contagious. Because some cancers are related to viruses.
Which causative agents can cause cancer?
Helicobacter pylori is a high risk factor for gastric cancer;
Liver cancer is related to hepatitis B virus. According to research, people infected with hepatitis B virus are 11.3 times more likely to develop liver cancer than healthy people;

Cervical cancer is related to human papillomavirus. According to research, high-risk human papillomavirus DNA can be detected in 99.7% of cervical cancer patients;
In addition, hepatitis C virus and EB virus are also closely related to the occurrence of liver cancer and nasopharyngeal cancer, respectively.
It is worth noting that it does not mean that infection with these viruses will definitely cause cancer, but the risk of cancer does greatly increase.
In summary, to avoid cancer, it is the right way to develop good living habits, pay attention to hygiene, have physical examinations on time, exercise and improve one’s own immunity.
