Prostate cancer is a cancer of the epithelium of the prostate gland-an
organ of the male reproductive system, located below the bladder
and in front of the rectum.
•
It is defined by an abnormal proliferation of the cells Of the prostate
gland epithelium) which have an abnormal tendency to break away
from the parent tissue, spread to nearby (such as bladder, rectum,
pelvic floor, pol lymph nodes, etc.) or distant sites (mostly bones, also
lungs, liver, etc.) having an overall weakening and destructive effect
on the body.
•
It usually occurs in older men

prostate gland.

The cancer breaches the prostatic capsule and invades adjacent organs such as
bladder neck, seminal vesicle, rectum, adjacent muscles, pelvic wall and/or lymph
nodes after breaking away from the prostate gland.

The cancer invades distant organs such as bones (spine, long bones, etc.), lung,
liver, etc. after breaking away from the prostate gland and spreading via the blood
stream. Prostate cancer has a strong tendency to metastasize to the bones.
Locally advanced prostate cancer and metastatic prostate cancer together are
called as advanced prostate cancer.

Stage-wise distribution of prostate cancer cases – An Indian Study
What causes prostate cancer and what drives its
progression?
The process of prostate cancer growth and spread can be visualized as
a process of 2 interdependent steps:
a.
Initiation of the cancer (Also called carcinogenesis
b. Further growth and spread of prostate cancer
a. Initiation of the cancer (Also called carcinogenesis)
This is because of damage to or mutation of the DNA inside
the nucleus of prostate gland epithelial cell(s).
This could be spontaneous or due to a genetic predisposition
(i.e. tendency) on account of:
b. Further growth and spread of prostate cancer
Once initiated, the growth and spread of cancer cells is driven or
promoted by the action of the male sex hormones called as androgens.
This is natural because these cells are part of the male reproductive
system whose structure and function is always supported by androgens
- mainly testosterone
The correct medical or scientific term for this process is "Androgen
Receptor or AR signaling". This is because though testosterone, which
is basically secreted by the testes (90% - 95%) and some other glands
(adrenal glands: 5% - 10%), it ultimately needs to bind to the androgen
receptor (located inside the prostate cancer cells) to carry out its
action.
Prostate cancer is a significant health concern among men, characterized by abnormal cell growth in the prostate gland. This cancer can spread locally or metastasize, leading to different stages such as localized, locally advanced, and metastatic prostate cancer. Dr. Hiralal Chaudhari explains the current burden of prostate cancer in India and outlines the outcomes based on the extent of spread in the body. Knowing the stages of prostate cancer is crucial for early detection and appropriate management.

Localized prostate cancer Localized prostate cancer The cancer is confined within the prostatic capsule - in one or both lobes of the prostate gland.
Locally advanced prostate cancer Locally advanced prostate cancer The cancer breaches the prostatic capsule and invades adjacent organs such as bladder neck, seminal vesicle, rectum, adjacent muscles, pelvic wall and/or lymph nodes after breaking away from the prostate gland.
Metastatic prostate cancer Metastatic prostate cancer The cancer invades distant organs such as bones (spine, long bones, etc.), lung, liver, etc. after breaking away from the prostate gland and spreading via the blood stream. Prostate cancer has a strong tendency to metastasize to the bones. Locally advanced prostate cancer and metastatic prostate cancer together are called as advanced prostate cancer.
