Skin Cancer
How does cancer spread?
In 3 ways:
- Cancer cells grow through the walls
of blood vessels and are carried by the blood
stream to other
parts of the body.
- They enter the lymphatic stream
and are carried to lymph glands.
- They grow directly from one tissue
to another
Is cancer a single
disease?
No. the term
"cancer" includes all forms of malignant growth.
Very many varieties
are known. These have certain characteristics in common though such as
uncontrolled growth a tendency to spread widely in the body and fatal
termination if not treated early and adequately.
They differ in certain
characteristics, such as location in the body, microscopic appearance, and
response to treatment.
Their histories of development may be quite dissimilar
and it is probable that the conditions which may precede them also differ
greatly.
How fast does cancer
grow?
There is no definite
rate of growth of cancer tissue; some types will grow more in a few weeks than
other types will, in several years.

How does a doctor tell if growth
is cancerous?
By performing a biopsy i.e. examining a small portion of the tissue under a microscope.
In advanced cases,
physical examination alone may reveal the diagnosis. But the chances of cure at
this late stage are very poor.
