Why is the focus of research focused on tumors?

The tumor microenvironment refers to the adjacent tissue cells and their various factors, including cytokines, growth factors, hormones and extracellular matrix, which are closely related to tumorigenesis, metastasis and drug resistance.

Summary: In fact, the tumor itself is a research hotspot, and it is estimated that it will not be a topic of exhaustion for a long time, and the research on him is interrelated rather than independent of each other, and its intricate relationship makes a pathway that people may not be able to figure out for a lifetime. The efficacy of radiotherapy for some tumors is certain, but for some tumors, it is accompanied by obvious results, so the innovation of radiotherapy technology has also become a concern for many radiotherapy researchers and clinicians.

First of all, it is a mistake to focus all the research on tumors, and it should be who the is the tumors.

You can understand normal cells as normal people, cancer cells as zombies, zombies are transformed from normal people, but they have more vitality and competitive advantages than normal people, and they are immortal, they eliminate normal people or infect normal people into zombies, and eventually the whole world is zombies. This is the trend of the times, as long as people live long enough, they will definitely get cancer, just like everyone in the zombie world must eventually become zombies. In addition, the process of normal cells transforming into cancer cells, and then metastasizing and spreading, or cancer cells dying on their own, includes all the processes that life can have, so the study of cancer is also the study of life itself.

If cancer is studied thoroughly, life is also studied thoroughly. The negative proposition is also true, it is impossible for human beings to understand the mystery of life, so it is impossible to study cancer thoroughly, and it is impossible to cure it.

I think one is the eating aspect, which is too greasy and too heavy in taste. Then there are bad living habits, staying up late, and not getting enough sleep. Meals are irregular. There is no good sleep time. The third is the problem of mentality, which is not relaxed and depressed every day.

Tumor formation is complex, and the main causes are general.

1. Genetics, genetic mutations or infections, etc., 2. Irregular diet, irregular work and rest, and the prevalence of smoking will be much higher than that of normal people, 3. Congenital immunity deficiency or decline, poor resistance, and easy infection.

The first reason is that people who smoke and drink often are particularly prone to diseases such as tumors, the second point is that people with irregular diets are basically prone to tumors, and the third point is that people who often overeat, you will find that such people are particularly prone to tumors.

Hello, tumor cancer is a new organism formed by the body under the action of various carcinogenic factors, a cell of the local tissue loses the normal regulation of its growth at the gene level, resulting in its clonal abnormal proliferation.

Tumors are generally divided into two categories: benign and malignant. All malignant tumors are collectively called cancer. Tumor tissues differ from the normal tissues from which they originate to varying degrees in cell morphology and tissue structure, and this difference is called atypia.

Atypia is the morphological manifestation of abnormal tumor differentiation. Small atypia indicates a high degree of differentiation, and large atypia indicates a low degree of differentiation. Distinguishing the magnitude of this atypia is the main histologic basis for diagnosing tumors and determining their benign and malignant nature.

The atypia of benign tumor cells is not obvious, and it is generally similar to its ** tissue. Malignancy is often overtly atypia. Malignant tumors with invasive growth can not only grow and spread (direct spread) at the primary site, but can also spread to other parts of the body through various routes**Migration).

From the perspective of **effect**, surgery and radiation are both local methods. Therefore, in addition to paying attention to local tumors, tumor chemists focus more on the spread and metastasis of malignant tumors. Their view of tumor ** is the view of cell exponential killing, so they emphasize the multi-course and full-dose drug method, in order to completely kill most of the tumor cells.

In the advanced stage of cancer, the cancer cells have metastasized, and the hope of this situation is generally not great, and it is recommended to treat it according to the specific advice of the doctor.

You are oversimplifying, malignant tumors are the main cause of death, and it seems that you have become completely comfortable with your "tumors".

Tumors are often formed by the continuous proliferation and reproduction of a transformed cell, and the natural growth history of a typical malignant tumor can be divided into several stages: malignant transformation of a cell, clonal proliferation of transformed cells, local invasion, and metastasis at the distal hand.

What you yourself thought was a "benign tumor" was, but it may not always be "benign", so be careful.

Since you didn't describe your "tumor" in detail, I generally understood it as a "sebaceous cyst" (commonly known as it in Chinese.

It is recommended to surgically remove it when it is not painful or itchy (for very small copies, general surgery in a regular hospital is sufficient).

Lipomas or fibroids can be surgically removed.
