Cancer
Two types of tumors
Benign and malignant
Benign
Do NOT turn into malignant
Malignant
Cells grow into nearby tissues
and spread to other parts of
the body via blood or lymph.
* Can still come back after
removal.
How cancers are named
After the body part in which it started
New tumors spread from tumor of origin
Called metastases
Bladder cancer in the lungs
Causes lung metastases
Cancer that is spread to another part of the body i.e. the lungs
Secondary lung cancer
Primary cancer
Located where the cancer started
Precancerous conditions
Atypia
Cells that are slightly abnormal
Metaplasi
means that there has been
a change to the types of cells that are
normally found in this area of the body.
The cells look normal but they aren’t
the type of cells that are normally
found in that tissue or area.
Dysplasia
means that cells are
abnormal, there are more cells than
normal, the cells are growing faster
than normal, and they aren’t arranged
like normal cells.
Carcinoma in situ
is the most severe
type of precancerous change. The cells
are abnormal but have not grown into
nearby tissue. Carcinoma in situ is
usually treated because it has a high
risk of developing into cancer.
People with precancerous conditions
Usually checked regularly so they can bebe treated quickly if changes begin more severe
Cancers stages often include
Size of tumor
Which part of organ has cancer
Whether cancer has spread 9metastasized)
Where it has spread
Staging cancer describes
cancer based on how
much cancer is in the body and where it is
when first diagnosed. This is often called the
extent of cancer.
Cancer stages
stage 0 – indicates that the cancer is where
it started (in situ) and hasn’t spread
* stage I – the cancer is small and hasn’t
spread anywhere else
* stage II – the cancer has grown, but hasn’t
spread
* stage III – the cancer is larger and
may have spread to the surrounding
tissues and/or the lymph nodes (part of
the lymphatic system)
* stage IV – the cancer has spread from
where it started to at least one other body
organ; also known as “secondary” or
“metastatic” cancer
Purpose of staging cancers
Treatment planning
Prognosis including chance of recovery
Predict treatment success
Cnacers in the same part of the body with the same stage tend to have
Similar prognosis
Cnacer grading is done by
Observeing cancer cells under microscope
Grading depends on
How different cancerlcells look from normal cells (differentiation)
Features of tumor like size and shape of cells and arrangement
Speed of cell proliferation
Whether there are areas of cell death
Low grade tumor
tend to grow slowly and are less
likely to spread.
Grade 3 cancer cells
High-grade cancers tend to grow more quickly and
are more likely to spread.
Don’t look normal
Prognostic factors for the cancer
Type of cancer
Subtype of cancer-based on the type ofc. ells or. tissue
