Cancer is the second leading cause of death in the world

Cancer is the second leading cause of death in the world, but not all cancers take human lives. Most early-stage cancers will not kill the person. Therefore, medicine now encourages each person to perform early cancer screening to detect the disease at an early stage, so the chance of survival will be much higher.

According to statistics of the International Agency for Research on Cancer (IARC): in 2018, there were 18.08 million new cancer cases worldwide, of which more than 9.5 million people have died from this disease.

The most common types of cancer in men are Liver cancer (21.5%), Lung cancer (18.4%), Stomach cancer (12.3%), Colorectal cancer (8.4%), Arch cancer (5%); The most common cancers in women are Breast (20.6%), Colorectal (9.6%), Lung (9.4%), Stomach (8.6%) and Liver (7.8%). The age-standardized cancer incidence in both sexes is 151.4/100,000 persons and the mortality rate is 104.4/100,000 persons.

In the US, an estimated 70% of cancer patients are diagnosed at late stages (III or IV), including diseases that can be screened and detected early by various methods. The chances of a cure for cancer increase when detected early. You need to pay attention to the state of your body and recognize some of the possible warning signs of cancer.

Cancer often develops silently for a long time before causing detectable clinical signs and symptoms. Sometimes cancer has no clinical symptoms and is only discovered during routine check-ups. Besides, when cancer causes clinical manifestations, the manifestations are diverse and unclear, easily overlooked and confused with other common benign diseases. As the disease progresses, the obvious clinical signs of the new cancer become more and more apparent

Cancers are becoming more and more common in the world

Cancer is a malignant disease of cells, when stimulated by carcinogenic agents, cells proliferate in a disorganized manner and do not follow the body’s control mechanisms for growth. Cancer is not a disease but a collective name for a collection of many diseases, which share the same basic characteristics of cancer and there are more than 200 different cancers in humans.

Cancer, depending on the extent of invasion to organs, blood vessels, nerves, or spread to the whole body. It can cause symptoms such as unexplained weight loss, fatigue, fever, persistent pain, digestive problems, swelling or lumps – swollen glands, skin abnormalities…

The earlier cancer is detected, the higher the cure rate. Proactive screening for early detection of cancer will make treatment more effective with lower costs. In addition to screening, understanding and recognizing the symptoms caused by cancer will help patients quickly go to medical facilities for timely diagnosis and appropriate treatment. Here are 10 common signs of cancer.

10 Common Warning Signs of Cancer

1. Unexplained Weight Loss

Weight loss is one of the early signs of cancer

Although weight loss is one of the early signs of cancer that patients may experience, the cause may be related to abnormalities in the digestive tract, or systemic disorders caused by cancer. If you experience sudden weight loss in a short time and lose more than 10% of your body weight but not for any specific reason (such as actively changing your diet – exercising to lose weight, or due to stress) ), the patient should go to the hospital to check.

2. Changes in the Skin

Whether it’s just a small pimple or a purple bump or a patch of scaly skin, if it doesn’t go away in a few days, you should see your doctor for a checkup. We often ignore small wounds on the skin and assume that they will go away on their own. This has created an opportunity for cancer to develop.

If you find a bump on your eyelid or a waxy patch of skin that doesn’t heal on its own within a few days, you should consult your doctor at the earliest.

3. Fatigue, weakness

Cancerous tumors use nutrients from the body to grow and spread, and can also secrete substances that disrupt metabolism as well as disrupt body activities. Patients may feel fatigue, weakness that does not improve despite rest, diet and lifestyle adjustments. At the same time, other symptoms caused by cancer (such as pain, weight loss, loss of appetite …) can also lead to this condition.

4. Fever

Fever can be a warning sign of cancer

High fever or persistent fever with no known cause, can be a warning sign of cancer (especially blood cancer), when the fever is repeated and often occurs at several times of the day ( evening, night…) accompanied by sweating.

5. Prolonged Pain

In the process of growing and spreading, cancerous tumors will put pressure on blood vessels and nerves in nearby tissues and organs, which can cause pain. The pain threshold is different for each person. Therefore, if you notice that the pain is persistent, new, and has no known cause, the pain does not decrease with basic pain relievers, or the pain level is getting worse, the patient should go to the hospital for examination soon. 

Depending on the type of cancer and the corresponding compression manifestations, the location of pain will be different. For example, some brain tumors can cause headaches that last and don’t go away even with painkillers; and conversely, not all brain tumors cause headaches.

Cramping pain in women during menstruation is considered normal, but you should not ignore prolonged pain near the pelvis and back as this is a sign of cancer. Pain in the upper abdomen is a sign of pancreatic cancer, while a tumor in the spine can cause terrible pain in the lower back.

6. Unusual Toileting

This is another sign that is often confused with constipation or irritable bowel syndrome. Abnormal bowel movements are an early sign of colorectal cancer. Another reason this sign can be overlooked is that many women experience constipation, bloating, and bowel changes in the lead-up to their period.

Tumors in the bowel, bladder, or prostate gland or compression from nearby organs such as uterine or ovarian tumors can affect bowel and urinary tract function, from That changes the patient’s bowel habits – urination. Patients may have bowel disorders (diarrhea, constipation) or urination disorders (frequent urination, urinary incontinence, painful urination, feeling of incomplete urination, weak urine flow, etc).

7. Unexplained Bleeding

Be careful with frequent bleeding

Depending on the organ where the cancer is located, the patient may experience abnormal bleeding in many different locations. Bleeding symptoms can manifest in many different forms, such as vomiting blood, coughing up blood, blood in the urine, or bloody stools. Vaginal and cervical cancer can cause abnormal vaginal bleeding between periods, after sex, or after menopause. In addition, prolonged bleeding under the skin (bruising) can also be a manifestation of cancer by causing dysfunction of blood clotting – hemostasis.

8. Prolonged Dry Cough

A dry cough that persists for more than 2-4 weeks, is not associated with an inflammatory airway disease, and is unresponsive to conventional treatments is considered one of the symptoms suggestive of bronchial cancer, metastatic cancer elsewhere compressing the pharynx – larynx – mediastinum. Persistent hoarseness is a symptom of vocal cord dysfunction (due to damage to the vocal cords, or damage to the nerves that control vocal cords), which may be a symptom of laryngeal cancer or Thyroid.

9. Problems Related to Eating, Digestion

Cancers of the face and neck, and cancers of the digestive tract can cause a number of problems related to eating. Cancer of the mouth, tongue, and nasopharynx can make patients feel like something is stuck in their throat, causing difficulty swallowing and swallowing for more than 2-4 weeks. Gastrointestinal cancer can cause symptoms such as bloating, loss of appetite, nausea – vomiting, stomach pain …

10. Lumps, Lymph Nodes on the Skin

Cancer occurs when abnormal cells grow out of control, forming a tumor or spreading to nearby lymph nodes. Therefore, lumps or nodes appearing anywhere on the body such as neck, armpit, breast, groin… can be a sign of cancer.

Depending on the location of the cancer and the extent of invasion to nearby organs – blood vessels – nerves, the symptoms caused by the disease may appear alone or in combination with other symptoms. For example, lung cancer with mediastinal lymph node metastasis can cause persistent dry cough and weight loss, fatigue; Stomach cancer in the early stages can cause digestive disorders (easy to confuse with other benign diseases of the stomach-esophagus such as ulcers, reflux…), after a while, it will cause loss of weight, fatigue.

Therefore, in addition to the need to adjust lifestyle and nutrition, healthy exercise to prevent cancer. You should be proactive in screening to detect cancers early. We also do not forget to “listen” to changes in the body, to detect the earliest abnormal symptoms, quickly visit medical facilities for early diagnosis, effective treatment.
