How much do you know about the six major physical signs of malignant tumors in the body?

Author: Huang Yanhong Duan Yuechu

Recently, a research team from Shanghai Jiao Tong University has made an important study in the field of medicine, revealing six obvious or potential manifestations that may occur in the body when there is a malignant tumor in the body. This research result is like a beacon, pointing out the direction for us in the fight against cancer, and has an important value and role that cannot be ignored. It can help us detect abnormalities in the body as early as possible, detect cancer in its early stages, buy precious time for subsequent treatment, and may even change the fate of patients and improve the cure rate of cancer and the survival rate of patients.

The human body is an ingenious system. When something abnormal happens, it will send us an alarm in a unique way. Malignant tumors are no exception, but these alarm signals are sometimes not so strong and can be easily ignored or mistaken for ordinary minor problems. Next, let's take a deep look at these 6 physical manifestations that may indicate malignant tumors and build a strong defense for the health of yourself and your family.

Persistent fatigue: a dangerous sign that your body is running out of energy

In the fast-paced modern life, fatigue seems to have become the norm for many people. It is normal to feel exhausted after a busy day. But if this feeling of fatigue persists for a long time and cannot be relieved no matter how much rest you take, then we need to pay great attention to it.

For example, Mr. Zhang, a 50-year-old office worker, used to be in good health, but recently, he always felt like he had been drained of energy. Every morning when he got up, he felt exhausted, and even climbing the stairs made him breathless, as if the "power" in his body had been completely depleted. At first, he thought it was because of the pressure from work and his age, so he didn't take it seriously. Until one time, the company organized a physical examination. When he received the physical examination report, he was completely stunned - liver cancer, this terrible disease, had quietly taken root in his body.

It turns out that when tumor cells grow wildly in the body, they consume a lot of the body's energy. At the same time, they also release inflammatory factors, which keep the body's immune system on high alert and continue to "work overtime." Under such a double blow, the body's energy distribution system is completely disrupted, and fatigue will naturally become more intense.

Cases like Lao Zhang are not uncommon. Many cancer patients have similar experiences in the early stages of their cancer. They often attribute this fatigue to work fatigue, stressful life, or aging, thus missing the best time for treatment. Therefore, if you find yourself suffering from fatigue for a long time, you must go to the hospital for a check-up in time and never take it lightly.

Unexplained weight changes: a warning sign of metabolic imbalance in the body

Changes in weight often reflect the health of the body. Under normal circumstances, weight gain or loss is closely related to our diet, exercise and other living habits. However, if there is a sudden and significant drop or gain in weight, and there is no obvious reason, it is likely that the body is sending us a danger signal.

Take Mr. Li for example. He is a person who loves life and pays attention to diet and exercise. But in just three months, he lost 15 kilograms. At first, he was secretly happy about his "successful weight loss", but not long after, he began to feel weak all over and even lost his appetite. He realized something was wrong and rushed to the hospital for a comprehensive examination. The result was like a bolt from the blue - a tumor had grown on his pancreas.

Malignant tumors are like naughty "troublemakers" that disrupt the body's normal metabolic patterns. They accelerate the decomposition of fat and protein, causing the body to lose weight rapidly without noticing. In addition, some tumors, such as ovarian cancer, can cause fluid accumulation in the abdominal cavity, leading to abnormal weight gain.

A study by Shanghai Jiaotong University clearly pointed out that unexplained sudden weight loss is a high-risk signal for malignant tumors, especially the risk of cancer in the gastrointestinal tract, pancreas and lungs, which need to be investigated. Therefore, if you find that your weight has changed abnormally, you must go to the hospital for a detailed examination in time to find out the real reason behind it.

Persistent pain: a strong warning from the body's alarm

Pain is the body's most direct "alarm", and it often sounds the alarm when cancer strikes. However, the pain in the early stages is often not severe, and sometimes occurs intermittently, making it easy for us to ignore it.

For example, Mr. Wang is a 40-year-old office worker. Due to the nature of his job, he needs to sit at his desk for a long time. Recently, he always felt a dull pain in his back. He thought it was muscle strain caused by sitting for a long time, so he bought some pain-relieving plasters and went to a massage parlor from time to time to relax. But this pain was like a "little devil" that could not be shaken off. It recurred and showed no signs of relief. Until one day, the pain suddenly intensified and he couldn't bear it anymore, so he went to the hospital for a check-up. The result shocked him. He was diagnosed with kidney cancer, and the cancer cells had metastasized to the lumbar spine.

The pain caused by cancer is usually persistent, and general painkillers are unlikely to provide significant relief. For example, dull pain in the bones may be an early sign of bone metastasis; dull pain in the chest may be a dangerous signal from lung cancer. Therefore, when you have persistent pain in a certain part of your body, do not delay, and be sure to seek medical attention in time and undergo a comprehensive examination so that the problem can be discovered as early as possible and treated in time.

Long-term low-grade fever: a silent battle between tumors and the immune system

A low-grade fever, a seemingly common symptom, usually reminds us of a cold or infection. But if a low-grade fever persists for weeks or even months and no clear cause can be found, it should not be taken lightly.

Xiao Li has been feeling a bit hot lately. When he took his temperature, he found that it was always around 37.5℃. He thought he had a cold, so he took some cold medicine, but the low-grade fever did not go away. This lasted for several months, and his body became weaker and weaker. He also had symptoms such as night sweats, fatigue, and loss of appetite. Later, he went to the hospital for a detailed examination and was diagnosed with leukemia.

It turns out that when tumor cells grow in the body, they stimulate a strong response from the immune system, leading to the release of a large number of inflammatory factors, which in turn cause low fever. Especially for blood system tumors such as leukemia and lymphoma, fever is often one of the earliest symptoms. Many people mistake this low fever for "false fire" or a minor illness and do not pay enough attention to it. However, research from Shanghai Jiaotong University shows that this long-term low fever is likely to be the body sending us an "invisible signal" to remind us that there may be a malignant tumor in the body.

Therefore, if a low fever is accompanied by symptoms such as night sweats, fatigue, and loss of appetite, you must go to the hospital as soon as possible for a blood test or imaging test to detect potential health risks in time.

Abnormal bleeding: a red alert from your body

A healthy body is like a well-oiled machine, with all parts working in harmony, and bleeding generally does not occur easily. However, if you find yourself experiencing abnormal phenomena such as blood in the stool, coughing up blood, or urine, or vaginal bleeding during periods other than menstruation, be alert, as this may be caused by a tumor.

Take Aunt Zhao for example. She is a 60-year-old retired woman who has always been in good health. But recently she found that she had blood in her stool. At first she thought it was hemorrhoids, so she bought some hemorrhoid cream. But after a while, the blood in her stool did not get better, but became worse. She realized the seriousness of the problem and rushed to the hospital for a check-up. After a colonoscopy, she was diagnosed with early rectal cancer.

Tumor cells are like a group of crazy "invaders". They will invade blood vessels or interfere with the body's coagulation function, leading to abnormal bleeding. Blood in the stool may be a manifestation of colorectal cancer, coughing up blood may indicate lung cancer, and blood in the urine requires the possibility of urinary tract tumors to be checked. This abnormal bleeding is like a "red alarm" issued by the body, and we must not ignore it. Once discovered, go to the hospital immediately for a detailed examination so that it can be diagnosed as soon as possible and treated in time.

Unexplained lumps or swellings: Palpable danger signs in your body

When lumps or swelling suddenly appear in certain parts of our body, especially when these lumps are hard, irregular in shape, and not painful when touched, we must be highly vigilant, as this may be an early manifestation of a malignant tumor.

For example, when the young Xiao Wang was taking a shower, she accidentally felt a lump in her breast. Since she didn't feel any pain, she didn't take it seriously. But as time went by, the lump gradually grew larger, and the lymph nodes under her armpits also swelled. She panicked and rushed to the hospital for a check-up. In the end, she was diagnosed with breast cancer.

Cancers such as breast cancer and thyroid cancer often present with painless lumps in the early stages. The research from Shanghai Jiao Tong University reminds us once again that if we find unexplained lumps or swellings in our bodies, we must go to the hospital for examination in time. Early detection of lumps and timely medical treatment are crucial to improving the treatment effect of cancer.
