Most of the possible signs and symptoms of cancer that we
notice turn out to be something that isn’t serious. For example, a new mole or
lump or a headache that won’t go away is not likely to be cancer, but should be
checked out by a doctor just to be sure. That gives you your best chance of
getting the problem treated, whether it’s cancer or something else. Treatment
usually works better the earlier it’s started.
It would be helpful if our bodies gave us a
clear message when we had cancer, but cancer is complicated. It’s a group of
diseases that can cause almost any sign or symptom, depending on where in the
body the cancer starts or even where it has spread. What makes it even more
complicated is that many other health problems that aren’t cancer can cause the
same signs and symptoms as cancer does.
Possible signs and symptoms of cancer
If you notice any of these signs and symptoms,
get them checked out – especially if they last for a long time or get worse.
It’s more likely that something that isn’t cancer is causing the problem, but
seeing a doctor is the only way to find out.
- Unexplained
weight loss: Losing 10 pounds or more
without knowing the reason
- Fatigue: Extreme tiredness that doesn’t get better with
rest
- Pain: Especially back pain, or a headache that doesn’t
go away or get better with treatment
- Skin changes: Any wart, mole, or freckle that changes color,
size, or shape, or that loses its sharp border should be seen by a doctor
right away. Other skin changes should be reported, too, including:
darkening, yellowing, reddishness, itching, and excessive hair growth.
- Sores
that do not heal: These
can be on the skin, in the mouth, or on the genitals.
- Change
in bowel habits or bladder function: Long-term
constipation, diarrhea, a change in the size of the stool, pain when
passing urine, blood in the urine, or a change in bladder function (such
as needing to go more or less often than usual)
- White
patches inside the mouth or white spots on the tongue: Smoking or other tobacco use can cause
pre-cancerous areas. If not treated, these patches or spots can become
cancer.
- Unusual
bleeding or discharge: This
can include coughing up blood, blood in the stool (which can look like
very dark or black stool), abnormal vaginal bleeding, blood in the urine,
or a bloody discharge from the nipple.
- Lump: This can be anywhere, but mostly occurs in the
breast, testicle, lymph nodes (glands), and the soft tissues of the body.
Some breast cancers show up as red or thickened skin rather than a lump.
- Indigestion
or trouble swallowing that
doesn’t go away
- Nagging
cough or hoarseness that
doesn’t go away
These signs and symptoms are more common, but
they aren’t the only indications of cancer. If you notice any major changes in
the way your body works or the way you feel – especially if it lasts for a long
time or gets worse – let a doctor know.
