NCCN Guidelines for Patients
Colon Cancer, Version 1.2014
You’ve learned that you have
melanoma skin cancer. It’s common
to feel shocked and confused. Part 1
reviews some basics about melanoma
that may help you better understand
this disease. These basics may also
help you start planning for treatment.
Layers of the skin
The skin is the largest organ of the body. The skin
has two layers. The outer layer, which can be seen,
is called the epidermis. The second layer, under the
epidermis, is called the dermis. The third layer, under
the dermis, is the subcutaneous tissue.
See Figure 1.

Trea ment guide:
First-time treatment
Stage I (T1) colon cancer
Stages I (T2), II, and III
colon cancer
Stage IV colon cancer
Part 5 is a treatment guide for when you are first
diagnosed with colon cancer. Treatment options are
organized by cancer stage.
In stage I (T1), the cancer has grown into the
submucosa but not beyond. These tumors are
sometimes called “polyps with canc r” because the
cancer has not grown far.
In stages I (T2), II, and III, the cancer has spread
beyond the submucosa. However, the cancer has not
spread to distant sites.
Stage IV is metastatic disease. The cancer has spread
to distant sites. This section focuses on treatment
options for colon cancer that has spread to the liver,
lungs, or both organs.
