Cancer itself is a disease caused by genetic mutations, what causes may be a breakthrough in maligna

Genetic reasons, either because of low immunity, irregular diet, staying up late at night, or often eating some high-salt and high-calorie foods, may lead to malignant tumors.

Smoking, drinking, staying up late, malnutrition, decreased body immunity, not eating fruits and vegetables, irregular work and rest time, not exercising, too much stress.

The root cause of cell carcinogenesis is that cancer-causing factors cause mutations in proto-oncogenes and tumor suppressor genes, which cause normal cells to classify and grow lesions and form cancer cells. Not only do the cells become more and more cancerous, but they also spread throughout the body.

In the simple understanding of middle school biology, it can be that the mutation of the tumor suppressor gene fails, resulting in the loss of the proto-oncogene, or the mutation of the proto-oncogene is no longer controlled by the tumor suppressor gene, or both mutations occur and become cancerous. But the reality is more complicated than that.

Generally, cell carcinogenesis is a multi-step, multi-gene, multi-factor induction, oncogenes for cell proliferation and differentiation is a positive regulatory process, and tumor suppressor genes are a negative regulatory process for cell growth and differentiation, so generally at different stages there will be different genes mutations until the completion of cell carcinogenesis, so generally proto-oncogenes and tumor suppressor genes are mutated at the same time.

Cell carcinogenesis includes mutations in genes such as proto-oncogenes and tumor suppressor genes, and at least several gene mutations are required to form cancer cells, so cell carcinogenesis is a cumulative effect.

Breast cancer: If a person's mother, sister, or daughter has breast cancer, then she has an increased risk of developing breast cancer.

Ovarian cancer: If a person's mother or sister has ovarian cancer, then she has an increased risk of ovarian cancer.

Colorectal cancer: If a person's parent, sibling, or sister has colorectal cancer, then they have an increased risk of colorectal cancer.

Thyroid cancer: If a person has patients with thyroid cancer in their family, then they have an increased risk of thyroid cancer.

Melanoma: If a person has patients with melanoma in their family, then they have an increased risk of developing melanoma.

Kidney cancer: If a person has patients with kidney cancer in their family, then they have an increased risk of developing kidney cancer.

Primary liver cancer: If a person has patients with primary liver cancer in their family, then they are at increased risk of developing primordial blind aborted liver cancer.

If a person has more than one member of their family who has cancer, then they are at a higher risk of developing cancer. If you have a family history, it is advisable to get early cancer screenings and regular check-ups so that potential cancers can be detected early.

Yes, yes.

1. First of all, correct the downstairs owner: it is not "tumor becomes cancer......Rather, "non-internal cancer tumors turn into cancer tumors......”

2. Tumors can be divided into "benign tumors and malignant tumors" according to benign and malignant tumors; According to the composition, it can be divided into "pink tumor, sarcoma, hematoma, pyomata ......According to the nature of the cancer, it can be divided into "cancerous tumors and non-cancerous tumors".

3. Any cancer, in fact, can be said to be caused by the further deterioration and escalation of non-cancer diseases - cancer. Carcinogenesis is the alteration of DNA data (which is the instinctive result of biological evolution, which "perfects" itself in order to adapt to a new environment). Of course, cancer can be regarded as a "perfect evolution" of mistakes and mistakes), which leads to the continuous regeneration of harmful cells (i.e., cancer cells, which are also disease cells corresponding to non-cancer diseases) in the production of metabolic cells.

Hello, inside the tumor.

Bai distorted du

Molecules are lacking due to self-inflicted nursing.

Electrons, in turn, want to seize the electrons of the neighboring endons of the DAO, and distort the neighboring molecules to cause cancer. In this way, a vicious circle of chain occurs, and a large number of distorted protein molecules will be formed, and when these distorted protein molecules reproduce and replicate, the base program, that is, the genetic code, will be confused and the gene will be mutated.

Carcinogenesis should occur only when both proto-oncogenes and tumor suppressor genes are mutated, which can also explain why cancer always occurs in people of a certain age, because the probability of all these mutations is low, so it takes a long time. However, cancer has congenital sensitivities, such as congenital defects in proto-oncogenes or tumor suppressor genes, which are more likely to become cancerous, so they will show a certain familial genetic tendency

Activation of proto-oncogenes is the root cause, but if the mutation of the tumor suppressor gene is inactive, its function is weakened, and the cells will replicate repeatedly in an uncontrolled state, eventually forming tumors and metastasizing

No, proto-oncogenes and tumor suppressor genes are originally in the genetic material, but their mutations can cause cancer.

Wrong. Proto-oncogenes and tumor suppressor genes are present in the body.

It is a mutation in both the proto-oncogene and the tumor suppressor gene.
