Persistent cough, a sore that refuses to heal,
unexplained weight loss and changing bladder
habits may seem harmless, but experts warn people not
to dismiss them and other key changes in the body, for
fear they could be a sign of something worse.
A survey by researchers on behalf of Cancer Research
UK found almost half of those displaying at
least one red flag for cancer did not visit their doctor,
thinking their symptoms are ‘trivial’.
1. A persistent cough (Lung Cancer):
Most lung cancers do not show any symptoms until they
have spread too far to be cured. But, symptoms do
occur in some people in the early stages of lung cancer.
A new cough that does not go away, or changes in a
chronic cough or ‘smoker’s cough’ can be an early
indication of the disease. In addition, chest pain linked to
coughing, deep breathing or lauging as well as
hoarseness and coughing up blood are early warning
2. A change in the appearance of a mole (Skin Cancer)
Melanoma, the most deadly form of skin cancer, can
appear anywhere on the body, but they most commonly
appear on the back, legs, arms and face and even underneath a nail.
Though not common, they often spread to other organs in the body, making them more deadly. The most common sign is the appearance of a new mole or a change in an existing mole.
Signs to look out for include a mole that is getting bigger, changing shape, changing colour, bleeding, becoming crusty or itchy or painful.
3. A persistent chance in bowel habits (Bowel Cancer)
The three main symptoms of bowel cancer are blood in the stools or faeces, a change in bowel habit, such as going more frequently, or having looser stools, and abdominal pain.
These symptoms are very common, and can easily be attributed to other conditions.
As the vast majority of people diagnosed with bowel cancer are over the age of 60, these symptoms become more important with age.
4. A sore that doesn’t heal (for Many types of cancer)
A sore or ulcer in the mouth that fails to heal is the most common symptoms of mouth cancer, according to the Cancer Treatment Centers of America.
Persistent pain in the mouth can also be a sign.
As for the rest of the body, experts at Cancer Research UK say a person should seek advise from a doctor if a spot, wart or sore doesn’t heal after several weeks, even if it is painless.
5. A persistent difficulty swallowing (Esophageal or Oesophageal Cancer)
A number of medical conditions can make it difficult to swallow.
The key sign of oesophageal cancer is difficulty swallowing. This problem may contribute to weight loss, which can also indicate the disease is present.
6. Unexplained weight loss (for a number of cancers)
Most people with cancer will lose weight at some point.
According to the American Cancer Society when you lose
weight for no known reason, it’s called an unexplained weight loss.
An unexplained weight loss of 10 pounds or more may be the first sign of cancer.
This happens most often with cancers of the pancreas, stomach, esophagus (swallowing tube), or lung.
7. A persistent change in bladder habits (Bladder or Prostate Cancer)
Problems urinating can include needing to pee urgently, more frequently, being unable to go when you need to, or experiencing pain.
A slow or weak urinary stream, or the need to urinate more often, especially at night, can indicate prostate cancer specifically.
Blood in the urine is also a sign.
With bladder cancer, the disease can cause changes in urination, including having to urinate more often, pain or burning during urination and feeling as if you need to go right away, even if the
bladder is not full.
8. An unexplained lump (for many types of cancer)
Many cancers can be felt through the skin, though typically they occur in the breast, testicle, lymph nodes and soft tissues of the body.
A lump or thickening of tissue can be an early sign of the disease, but it can also indicate some forms of the disease are in an advanced stage.
You should visit a doctor, especially if you have just found a lump or noticed a lump has grown in size.
The American Cancer Society note that some breast cancers can show up as red or thickened skin rather than a lump.
9. Persistent, unexplained pain (for many types of cancer)
Pain can be present in the early stages of a number of cancers, but especially with BONE and TESTICULAR cancers. A headache that will not go away or get better with treatment can be a sign of a brain tumor.
Furthermore, back pain can indicate cancer of the COLON, RECTUM, or OVARY.
In most cases, where pain is felt and cancer is diagnosed, it is an indication that the disease has spread from its primary location in the body.
10. Unexplained bleeding (for many types of cancer namely Bowel, Cervical or Vulval Cancer)
In both the early and late stages of the disease, unexplained bleeding can occur.
Coughing up blood can be a sign of LUNG cancer, while
blood in the stool is an indication of COLON or RECTAL/RECTUM
Cancer of the CERVIX or the ENDOMETRIUM or the lining of the uterus can cause abnormal vaginal bleeding.
Blood in the urine can indicate a person is suffering from BLADDER, KIDNEY or PROSTRATE cancer and a bloody discharge from the nipple may be a sign of BREAST cancer.
