testicular
cancer
Testicular cancer is the most common form of cancer in men
between the ages of 15 and 45. Currently about 2000 men a year develop the disease
in the UK.
The incidence of testicular cancer has risen dramatically
over the last 20 years, and doctors are baffled as to why this is.
Men with one or more undescended testes have a greatly increased
risk. This condition may increase the risk of testicular cancer by five to ten times.
Testicular cancer can have a strong genetic component. First degree
relatives (brothers, fathers or sons) of testicular cancer patients
have an increased risk of developing this disease. Inherited genetic factors may play a role in up to one in five testicular cancers.
Scientists at The Institute of Cancer Research co-ordinate an international team of researchers which aims to identify genes implicated in susceptibility to testicular cancer. Studies by this group have initially highlighted a region on the X chromosome that may contain a testicular cancer gene, but the actual gene has yet to be identified and there are likely to be several testicular cancer genes to identify.
Scientists do not know what percentage of cases are caused by an
inherited genetic susceptibility, but some estimates put the figure
at as high as 30% of all cases.
Most (up to 99%) of testicular cancers can be cured if caught
at an early stage. Even when these tumours spread they can still
be cured in approximately 95% of cases.
Testicular cancer normally presents itself as a lump in the testicle.
Regular examination of the testicle can, in most instances, detect
testicular cancer at an early stage but neglect can lead to presentation
with advanced cancer. If a lump or change in the testicles is identified, a GP will arrange for a testicular ultrasound which would then indicate if the lump was benign or a possible tumour.
The Institute was responsible for the development of carboplatin,
a new drug which is highly successful in treating testicular cancer
and has led to today's high cure rate.
Treatment for testicular cancer may be very intensive, but most
patients cured of testicular cancer have no long-term side effects
from treatment. A small proportion of patients will become infertile
after chemotherapy treatment. Other side effects of treatment are
uncommon but may include damage to the nerve endings, hearing, spasms
in the blood vessels and possibly an increased risk of heart disease
in the future. There may be a small increased risk of developing
other cancers. The risks of these problems are fewer if the cancer
is treated early.
What are the symptoms?
- a lump in either testicle
- any enlargement of a testicle
- a feeling of heaviness in the scrotum
- a dull ache in the abdomen or groin
- a sudden collection of fluid in the scrotum
- enlargement or tenderness of the breasts
If you have any of these symptoms, go and see your doctor.
