2. • The most common type of prostate cancer is
called acinar adenocarcinoma. It affects 90
percent of prostate cancer patients. Acinar
Adenocarcinoma begins in the prostate gland
cells.
3. • Many people with acinar adenocarcinoma are
not expected to see the disease spread. But some
cancers may grow quicker than others.
Symptoms may include an urgency to urinate,
difficulty passing urine, pain while urinating and
blood in the urine or semen. A biopsy can be
used to determine which type of prostate cancer
is present.
4. Ductal Adenocarcinoma
• Ductal adenocarcinoma cancer forms in cells
that line the tubes of the prostate gland. This
type of cancer grows and spreads quickly.
Because of this, some men may have an
advanced state of prostate cancer when they are
first diagnosed.
5. • Surgery is the most common treatment for
ductal adenocarcinoma as it does not respond
well to hormone therapy. Chemotherapy may be
needed as well.
6. Transitional Cell or Urothelial Cancer
• Urothelial cancer begins in the urethra or the
tubes that are responsible for carrying urine.
Urine moves through the male body by passing
through the urethra from the bladder and finally
through the outside of the body.
7. • Urothelial cancer may be spread from the
bladder to the prostate gland and nearby tissues.
Surgery is needed to remove this type of cancer
from the body. If surgery cannot be performed,
chemotherapy may be suggested.
8. Squamous Cell Cancer
• Squamous cell cancer begins in flat cells called
squamous cells that cover the prostate gland.
Cancerous squamous cells grow and spread
quickly so most men see advanced types of this
cancer when first being diagnosed. Treatment
may include surgery.
9. Carcinoid of the Prostate
• Carcinoid of the prostate occurs when tumors
occur in the prostate gland. These tumors start
from cells in the neuroendocrine system that are
made up of glands and specialized nerve cells.
10. • It is a rare type of cancer that grows slowly.
There may be no symptoms for years with this
kind of cancer. Doctors may treat the disease by
monitoring it only. Tumors that grow quickly
will need to be removed.
11. Small Cell Cancer
• Small cell cancer occurs as a result of a type of
neuroendocrine tumor that consists of small
round cells. This type of cancer is difficult to
determine by a prostate-specific antigen test.
12. • Because of this, small cell cancer is more
difficult to detect. It also grows and spreads
quickly. Chemotherapy is the recommended
form of treatment as small cell cancer does not
respond to hormone therapy.
13. Sarcoma and Sarcomatoid Cancer
• The last type of rare prostate cancer is called
sarcoma and sarcomatoid cancer. This kind of
cancer begins in muscle cells. These cancerous
cells grow quickly.
14. • Leiomyosarcoma is the most common type of
prostate sarcoma found in adults. Men between
the ages of 35 and 60 are most at risk for this
type of prostate cancer.
15. • Sarcomatoid cancers contain a mixture of
adenocarcinoma and sarcoma cells. Treatment
of these types of cancers includes surgery to have
the entire prostate removed. Radiotherapy and
chemotherapy may follow surgery.
