The word "cancer" is a frightening presence for many people. It represents not only physical pain, but also mental torture. However, referring to certain diseases as "cancer" may not be accurate and may even trigger unnecessary panic and misunderstanding.
In modern medicine, we are increasingly aware that each disease has its own unique ** and pathological process. Some diseases, although classified as "cancer", may actually have a pathogenesis and biological behavior that can be very different from true cancer.
The word "cancer" also carries a certain pejorative and discriminatory connotation. It seems to imply that these diseases are **, terrible, and even immoral. Cancer is not terrible, it is not a fatal disease. With the advancement of modern medicine, many cancers can be effectively controlled, and possibly even completely, through early detection and science.
Tumors
Tumor is a new organism formed by the abnormal proliferation of local tissue cells under the influence of various tumorigenic factors. Its form is a space-occupying lumpy protrusion, like a vegetation, hence its name. Tumors can be divided into two categories: benign and malignant.
Benign tumors are often called "tumors", while malignant tumors are called "carcinomas" if they originate from epithelial tissue, and "sarcomas" if they originate from mesenchymal tissues. Some malignant tumors, such as malignant lymphoma, seminoma, leukemia, Hodgkin's disease, etc., can also be called "tumor" or "disease".
Cancer
In the medical field, carcinoma refers to a malignant disease that originates in the epithelial tissue, and it occupies the most common position among all malignancies. In contrast, malignant tumors that originate in mesenchymal tissues are collectively referred to as sarcomas. However, there are some malignancies that do not follow the above nomenclature principles, such as Wilms tumor and malignant teratoma. In general, it is customary to refer to all malignancies collectively as "cancer".
Tumors and cancers, although they are only one word apart, have very different meanings. Tumour is a word that covers a wide range of topics, benign and malignant. Cancer, on the other hand, is a malignant tumor, which we often call a malignant tumor. To understand the difference between the two, we can do it from the following aspects**.
First, let's look at benign tumors. Benign tumors grow relatively slowly, have an intact capsule, and are mostly cystic. This tumor does not metastasize or, therefore, after surgical removal, the patient has a good chance of getting ** and less likely to have ** or metastasis. However, malignant tumors grow at a completely different rate. It grows very fast, has blurred borders, and does not have a complete envelope. Most of these tumors are solid, prone to calcification internally, and extremely abundant in blood**. Because of these properties, malignant tumors are prone to lymph node metastasis or metastasis to distant organs. Even if surgical resection is performed, it is highly susceptible to ** and systemic metastases, posing a serious threat to the patient's life. 
From the above comparison, we can clearly see the significant difference between tumor and cancer. While they both involve abnormal tissue growth in the human body, their nature, growth characteristics, and effects on patients are vastly different. In our daily lives, we need to have a correct understanding of these two diseases so that we can take appropriate preventive and ** measures when necessary. Low-risk prostate cancer
Like those at low risk of prostate cancer, their tumors are confined to the prostate and the PSA value may not exceed 20, which indicates that the cancer cells have not metastasized. For this type of cancer, the mortality rate is not high, and the disease progresses relatively slowly. As a result, some patients do not deteriorate and their bodies are not affected much after years of being diagnosed.
Modern clinical medical research reports show that the survival time of some cancer patients can even reach more than 10 years. Therefore, we do not need to worry too much, as long as we pay attention to semi-annual or quarterly physical examinations, we can detect and curb the possibility of cancer in time. As for this case, we don't need to overdo it.
Thyroid cancer
In the field of clinical medicine, the 10-year survival rate for thyroid cancer is as high as more than 9%, indicating that the prognosis of this cancer is relatively good. In fact, most thyroid cancers are benign, and only a small percentage may worsen. However, thyroid cancer is not classified as cancer because of its relatively low diagnosis and ** rate in the early stages. For most patients with thyroid disease, they can take medications under the guidance of their doctors, monitor them regularly, and avoid the spread of cancer cells and serious effects on the body. Of course, there is still a 5% chance of exacerbation, so aggressive surgical excision is required. Early breast cancer
For many female friends, the term breast cancer is no longer unfamiliar, and it is now appearing more and more frequently in women's diseases. However, breast cancer is not as scary as people think. If it can be detected early, its ** effect is quite considerable, and even more than ninety percent of patients can successfully defeat the disease, and the ** probability is relatively low. This means that even if you get breast cancer, you have a half chance of being able to**. 
With the rapid development of modern medical technology, the rate of breast cancer is also increasing year by year. This gives us an important reminder: early detection and early ** are the keys to avoiding breast cancer lesions. Therefore, every woman should be vigilant and pay attention to her physical condition from time to time, in order to detect and carry out breast cancer in time at an early stage**. Symptoms of early-stage cancer are often non-specific and can be easily overlooked. For example, symptoms such as fatigue, loss of appetite, weight loss, etc., can easily be considered a manifestation of excessive fatigue or other common diseases. Therefore, we need to keep an eye on our physical condition at all times and pay attention to any subtle changes.
The first is a persistent cough, which can be a sign of lung cancer. If you smoke for a long time or are exposed to harmful substances, you need to be especially vigilant. This is followed by abdominal pain and diarrhea, which can be a manifestation of colorectal cancer. If you have a family history or symptoms such as long-term constipation and diarrhea, you need to get checked early. In addition, the appearance of ** lumps, nipple discharge, **induration, etc. in the breast are also signs of breast cancer.
Of course, these symptoms don't necessarily mean cancer. However, if you have more than one symptom and it lasts for a long time, it is advisable to go to the hospital early for a check-up. The doctor will conduct relevant examinations and diagnoses based on your symptoms and physical condition.
In conclusion, early detection of cancer is very important for ** and prognosis. We need to keep an eye on our physical condition and be aware of any subtle changes. If symptoms are suspected, get tested and ** as soon as possible. Only in this way can we better defeat the formidable enemy of cancer.
Surgery is not the only option, but requires a comprehensive evaluation according to the patient's specific situation. Blindly, there may be unnecessary risks and harms. In clinical practice, there are many examples where surgery that is not adequately evaluated may lead to unnecessary indications for surgery.
For example, when it is found that the cancer has already adhered or metastasized, surgery may not be able to proceed and the incision may even need to be closed, causing a double blow to the patient, both physically and psychologically.
As early as 2002, the Handbook of Clinical Oncology compiled by world-renowned oncologists organized by the International League Against Cancer has clearly pointed out that in lung cancer and other tumor diseases, it is necessary to carefully evaluate the extent of the patient's lesions before thoracotomy surgery.
In fact, more than two-thirds of lung cancer patients are diagnosed without an indication for surgery. In this case, forcing the surgery may have worse consequences, and not rushing to the surgery may be a better option.
Therefore, for the treatment of cancer, we need to comprehensively consider the patient's condition, physical condition, age, psychology and other factors to formulate a personalized plan. When choosing whether to undergo surgery, it is necessary to fully evaluate the pros and cons of surgery and the risk-benefit ratio for patients, and avoid blind and unnecessary surgery. At the same time, we also need to continue to explore new methods and technologies to improve the efficacy of cancer and the quality of life of patients.
