CANCER
In 2020, 19.300 million people in the world were diagnosed with this disease that claimed more than 10 million lives, thus becoming the second cause of death worldwide and in 2030 it would be the first cause of death in the world, still with technological advances.
WHAT IS CANCER?
The word cancer is used to describe a group of diseases that can appear in any organ of the human body.
These diseases are characterized by the development of abnormal cells that grow uncontrollably due to the fact that there are important alterations in the mechanisms of regulation of cell growth.
To understand cancer, it is necessary to know a little about the cells that make up the tissues and organs of our body.

WHAT IS THE CAUSE
FROM CANCER?
The transformation of a normal cell into a tumor cell is a multifactorial process and usually consists of the progression from a pre-cancerous lesion to a malignant tumor. These alterations are the result of the interaction between the individual's genetic factors and three categories of external agents, known as carcinogens.
There are different types:
.
Physical carcinogens , such as ultraviolet and ionizing radiation.
Chemical carcinogens such as asbestos, components of tobacco smoke, aflatoxins (food contaminants), or arsenic (drinking water contaminant)
Biological carcinogens such as infections caused by some viruses, bacteria, or parasites.
About 30% of cancer deaths are due to five dietary and behavioral risk factors: high body mass index, reduced fruit and vegetable intake, lack of physical activity, tobacco use, and alcohol use.
Tobacco use is the most important risk factor, since it is the cause of more than 22% of cancer deaths in general, and around 71% of lung cancer deaths worldwide.

PREVENTION AND DETECTION
There is no sure way to prevent cancer, but there are steps that can lower your chances of getting it. Actions and substances that must be taken into account to reduce the possibility of getting sick.
At least one third of all cancer cases can be prevented. Prevention is the most cost-effective long-term strategy for cancer control.
01
REDUCE THE CONSUMPTION OF
ALCOHOL AND TOBACCO
05
GO TO THE DOCTOR REGULARLY, AND GET CHECKS
GENERAL PERIODICALLY.
02
DO NOT EXPOSE YOURSELF DIRECT
MIND AND BY EPISODES
EXTENDED TO UV RAYS AND SUNLIGHT
06
AVOID SEDENTARISM
03
BRING A FOOD
BALANCED
07
DO PHYSICAL EXERCISES
04
THERE ARE VACCINES THAT
REDUCE THE RISK OF
CANCER
08
AVOID CANNED MEALS, SAUSAGES, PREPARED MEATS
GENERAL SIGNS AND SYMPTOMS
WEIGHTLOSS
INEXPLICABLE
Most people with cancer will experience weight loss at some point. When you lose weight for no apparent reason, it is called unexplained weight loss. Unexplained weight loss can be the first sign of cancer. This occurs most often in the case of pancreatic, stomach, esophagus, or lung cancer.
FEVER
Fever is very common in cancer patients, although it occurs more often after the cancer has spread from where it started. Almost all patients of
Cancer will experience a fever at some point, especially if the cancer or its treatments affect the immune system.
TIREDNESS
Tiredness is extreme exhaustion that does not improve with rest. It can be an important symptom as the cancer progresses. In some can-
ceres, like leukemia, tiredness can occur at first. Some colon or stomach cancers can cause blood loss that is not obvious.
PAIN
Pain can be an early symptom of some cancers, such as bone cancer or testicular cancer. A headache that does not go away or is not relieved with treatment may be a symptom of a brain tumor.
Back pain can be a symptom of colon, rectal, or ovarian cancer.
CHANGES IN
THE SKIN
Along with skin cancers, some other cancers can cause skin changes that can be seen. These signs and symptoms include:
Darkening of the skin (hyperpigentation).
Yellowing of the skin and eyes (jaundice).
Redness of the skin (erythema) Itching (pruritus) Excessive hair growth.
PROGRESS
Liquid biopsy
Advances in science, which are very important in the detection of cancer, are already gaining more importance in the role of liquid biopsy and the follow-up of some tumors such as lung and colon cancer.
.
The liquid biopsy consists of the determination of tumor cells in the blood, to carry out molecular investigation of the tumors, that is being observed in a broader way in lung cancer, in colon cancer and more in breast cancer.
.
They are diagnostic methods that are allowing a greater understanding of the biology of the tumor.
