World Cancer Day: the most common types and the most dangerous ones
World Cancer Day 2022 reminds us that humanity is still fighting

On February 4 of each year , World Cancer Day is celebrated. A commemorative date both to remember those who succumbed to the disease, and to continue the fight.

Cancer is one of the most deadly diseases that a human being can suffer. From his wisdom, it is the object of constant study to consolidate a better perspective of life for patients.

What is cancer? Knowing its deepest concept

Cancer is the term used by the medical community to encompass a wide range of diseases. Each and every one of them is characterized by abnormal growth, reproduction and migration of carcinogenic cellular components.

Depending on the magnitude or severity of the process, they slowly or quickly invade the underlying tissues. Over time, without adequate therapy, it spreads to various organs or systems, causing severe multi-organ failure, a process known as metastasis.

Unlike normal cells, those with oncogenic purposes are independent and do not obey regulatory signals. They are uniquely designed to multiply exponentially, without suffering the consequences of programmed cell death (apoptosis).

When they become obvious enough, the cell clusters produce what are called tumors. Masses of abnormal tissue that grow at the expense of healthy tissue, altering its physiological function.

Tumor masses can be benign or malignant according to their predisposition or behavior

Although not all of them cause serious consequences, very few are classified as benign tumors. Therefore, in case of any suspicion, the ideal is to go to a specialized medical consultation to quickly undertake the appropriate treatment.

The most common types of cancer based on the World Health Organization

The World Health Organization (WHO) is one of the entities that remains in front of the fight against cancer. In this sense, it is the main promoter of campaigns aimed at avoiding or eradicating risk and predisposing factors.

After extensive observation and research, he concluded that mankind routinely suffers from certain known types of cancer. Since then, he has dedicated himself to faithfully studying their incidence, apparent origins and possible cures. Within the top, the following are sighted:

  1. Breast cancer

  2. Lung cancer.

  3. Colorectal cancer.

  4. Prostate cancer.

  5. Skin cancer.

  6. Stomach cancer.

The sum of all the cases gathered between each of these types of cancer, exceeds 10 million souls. All of them passed throughout 2021 as such.

And which are the deadliest according to the WHO?

Precisely all of the above have an intrinsic lethal potential. However, for practical purposes, those with the highest number of deaths behind them will be mentioned on a statistical basis. Diseases that, in a short time, consume the lives of patients without being able to do anything.

Lung cancer

It is the second class of deadly cancer in both men and women in almost 10% of the cases studied. The last survey carried out in 2020 showed a figure of almost 2 million deaths in total, due to this pathology.

Given this, the Centers for Disease Control and Prevention have warned of its prevalence associated with cigarettes. Those with a chronic or long-term tendency to smoke have a 27-fold increased risk of suffering from AC (cancer) of the lung.

In advanced conditions, lung cancer is incompatible with the development of life

In fact, the practice in question increases by up to 90% the chances of dying from said pulmonary disease. Consequently, campaigns against smoking and the indiscriminate sale of these products continue to be reinforced.

Colorectal cancer

It is the third type of cancer with deadly qualities in both the female and male gender. In the same survey carried out in 2020, it was found that almost 1 million people died at the cost of the disease.

As its name indicates, it is the cancerous affectation that manifests itself at the level of the colon or rectum. However, it does not mean that it cannot be a protagonist in other areas of the digestive system that are higher.

They are a direct consequence of preexisting chronic inflammatory states such as colitis, Crohn's disease, diverticulitis, and intestinal polyps. In turn, the American Cancer Association established its genetic or hereditary predisposition.

Breast cancer

Breast cancer is, at the same time, the most common and deadly cancer in relation to women. Its incidence is practically palpable from an early age, being secondary, in the majority, to important hormonal deficits or imbalances.

In 2020, it killed approximately 700,000 people. Deaths that were registered in both developed and underdeveloped countries. An alarming fact that suggests that it is a disease that is not afflicted by borders.

Together, the WHO speaks that it represents a higher prevalence in particular. The level of patients diagnosed since 1930 has remained almost stable, showing that it is more present than ever.

The fight against breast cancer is also a very widespread strategy at international level

Figures that do not go unnoticed and lead to the conclusion that 1 in 12 women will suffer from the disease. Therefore, the WHO launches a call for awareness, promoting knowledge of risk factors and advocating good medical habits.

Other deadly cancers

Lung, colorectal and breast cancer are not only common but life-threatening. Even so, there are two other types of cancer with harmful properties for the body.

In retrospect, gastric and liver cancer caused more than 1.5 million deaths. The sum of both scenarios also reduces to a worrying horizon.

On the one hand, it has been proven that gastric cancer is secondary to bacterial infections by Helicobacter Pylori. Pathogen that alters the protective lining of the stomach and causes an inflammatory response with carcinogenic potential.

On the other side, liver cancer is the direct result of distant metastases. Commonly, other neoplasms first spread to the liver, causing the abnormality in question. At the same time, some percentage of cases is derived from hepatic steatosis, hepatitis and more.

The WHO campaign that glimpses the keys to avoiding cancer

The World Health Organization leads the battle against the disease. As a result, it encourages a campaign where it highlights some key and simple guidelines to reduce the risk of cancer.

Within it, prioritize daily physical activity in intervals of half an hour as such. This should be complemented with a balanced diet rich in relevant nutrients. In this way, the risk of obesity or chronic inflammatory disorders will not have a place.

As an additive, it emphasizes fighting the bad habit of smoking and alcoholism. In another area, it recommends being up to date with the vaccination schedule against diseases such as HPV and hepatitis B.

Among other crucial tips, he suggests not exposing your skin too much to ultraviolet radiation. Much less to ionizing radiation, environmental pollution or toxic waste for any reason.
