There is a big difference whether you diagnose the disease in early stage or later, that depends on recognizing the early symptoms on which depends weather you will survive.
In early stage of cancer there is a big chance to beat the cancer cells if you aware of it sooner than later.
There are different kinds of cancer so you should make regular checkups to your doctor if you notice any of these symptoms.
Sudden weight loss
Weight loss is common among people with cancer and is often the first noticeable sign of the disease. As many as 40% of people with cancer report unexplained weight loss at the time of diagnosis, and up to 80% of people with advanced cancer experience weight loss and cachexia, or wasting, which is the combination of weight loss and muscle mass loss. Weight loss and muscle wasting also often come with fatigue, weakness, loss of energy, and an inability to perform everyday tasks.
You may lose your weight when you have breast and lung cancer or colon cancer.
This is as a result of when cancer goes to the liver, it weakens its function, which is to eliminate toxins and regulate the appetite.
Shortness of Breath or Wheezing
Sometimes this sensation is described as a tight or crushing feeling in the chest. The spread of lung cancer can cause blockages in the major airways or the buildup of fluid around the lungs (pleural effusion), causing a shortness of breath.
Wheezing can be described as a high-pitched whistling that occurs when you breathe out. It’s caused by constricted air passages, which may be the result of a tumor.
Constant infections or fevers
A fever isn’t necessarily a cause for alarm. Fever seems to play a key role in fighting infection. Persistent fever can signal a hidden infection, which could be anything from a urinary tract infection to tuberculosis. In some cases, cancerous (malignant) conditions — such as lymphomas — cause prolonged or persistent fevers, as can some medications.
Chest pain and persistent cough
Cough: A persistent cough that doesn’t go away is one of the most common symptoms of lung cancer. Most people get a cough from time to time, but if it persists, produces a lot of mucus or has a deeper or hoarse sound then have it checked out. If you notice a friend or a family member persistently coughing advise them to see their family doctor. Do not dismiss a persistent cough as a ‘smoker’s cough‘.
Chest Pain: Chest pain can sometimes be the first sign of lung cancer and is usually caused from the tumor extending into the lung lining or the ribs and muscle of the chest wall. Chest pain associated with lung cancer is often described as persistent, aching and dull. Any incidence of chest pain should always be checked by a doctor.
Exhaustion and weakness
See your doctor if after getting enough sleep and rest you still feel weakness or fatigue.
Blood in the stool may be a sign of bowel cancer, and blood in the urine can be an indication of UTI, which can be a result of kidney or bladder cancer.
Irregular vaginal bleeding is the most common symptom of invasive cervical cancer. The bleeding may occur between menstrual periods or after sex. Sometimes, it shows as blood-streaked vaginal discharge, which often gets dismissed as spotting.
Vaginal bleeding can also occur in postmenopausal women who no longer have menstrual periods. This is never normal and could be a warning sign of cervical cancer or other serious problem. You should go to the doctor if this happens.
Especially in the case of older people, the change in the bowel movements which persists longer than a month is a symptom of bowel cancer.
Unusual lumps or swelling
Persistent lumps or swelling in any part of your body should be taken seriously, including in the neck, armpit, stomach, groin, chest, breast or testicle. See your doctor to have it checked out.
In the case of a throat or esophageal cancer, the person may have troubles swallowing or may feel that there is a food in the chest or throat that aggravates over time.
Pelvic or abdominal pain
If you feel pain in the pelvic or abdominal area that could be a sign of having ovarian cancer. Women who have not conceived and have cancer patients in their families are at higher risk to develop this disease.
