Cancer Cells
Introduction
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or
lymph with abnormal cells. Cell division is a normal process used by the body for growth and
repair. A parent cell divides to form two daughter cells, and these daughter cells are used to
build new tissue or to replace cells that have died because of aging or damage. Healthy cells
stop dividing when there is no longer a need for more daughter cells, but cancer cells continue
to produce copies. They are also able to spread from one part of the body to another in a
process known as metastasis.
What are Cancer Cells?
Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other
parts of the body.
Cancerous tumors spread into, or invade, nearby tissues and can travel to distant places in the
body to form new tumors (a process called metastasis). Cancerous tumors may also be called
malignant tumors. Many cancers form solid tumors, but cancers of the blood, such as
leukemias, generally do not.
Benign tumors do not spread into, or invade, nearby tissues. When removed, benign tumors
usually don’t grow back, whereas cancerous tumors sometimes do.

Cancer cell is an acid eater. So if you starve
them don't give them any more acid it will
turn to; shrinkage, tumor, cyst.
Differece between Cancer Cells and Normal Cells?
Cancer Cells
Normal Cells
- Grow in the absence of signals telling them
to grow.
- Normal cells only grow when they receive
such signals.
- Invade into nearby areas and spread to other
areas of the body.
- Normal cells stop growing when they
encounter other cells, and most normal cells
do not move around the body.
- Trick the immune system into helping cancer
cells stay alive and grow.
- Rely on different kinds of nutrients than
normal cells.
How Does Cancer Develop

substances in the environment, such as the
chemicals in tobacco smoke and ultraviolet
rays from the sun.
they were inherited from our parents.
Cancer is a genetic disease—that is, it is
caused by changes to genes that control the
way our cells function, especially how they
grow and divide.

Cancer love Sugar. Sugar comes in many different forms, but the simplest form is a single
molecule called glucose. All cells, including cancer cells, use glucose as their primary fuel.
How does cancer arise and why is it so complex?
Since cells grow and replicate faster within tumors, the chance that damaged cells will
accumulate more DNA variants increases. This, in-turn, can grow the size and speed of a
tumor’s development. Despite these challenges, the research community remains strong,
creative, and dedicated to finding treatments, and more people are surviving cancer than ever
before.
Types of Genes that Cause Cancer
The genetic changes that contribute to cancer tend to affect three main types of genes:
o
Proto-oncogenes are involved in normal cell growth and division.
o
DNA repair genes are involved in fixing damaged DNA.
o
Tumor suppressor genes are also involved in controlling cell growth and division.

According to Dr. Jed Fahey scientific
research, that Broccoli Sprouts have 20 to
100 times more of the Anti-Cancer
properties.
When Cancer Spread to other tissues?
A cancer that has spread from the place where it first formed to another place in the body is
called metastatic cancer. The process by which cancer cells spread to other parts of the body is
called metastasis.
Metastatic cancer has the same name and the same type of cancer cells as the original, or
primary, cancer. For example, breast cancer that forms a metastatic tumor in the lung is
metastatic breast cancer, not lung cancer.
In other cases, the primary goal of treatment for metastatic cancer is to control the growth of
the cancer or to relieve symptoms it is causing. Metastatic tumors can cause severe damage to
how the body functions, and most people who die of cancer die of metastatic disease.

According to Dr. Thomas Siegfried from
Boston College, has said in his research that
if you complete a seven day water fast once
a year you would reduce your risk of any
cancer by 95% because of

Types of Cancer
There are more than 100 types of cancer. Types of cancer are usually named for the organs or
tissues where the cancers form. For example, lung cancer starts in the lung, and brain cancer
starts in the brain. Cancers also may be described by the type of cell that formed them, such as
an epithelial cell or a squamous cell.
Here are some categories of cancers that begin in specific types of cells:
Carcinoma's are cancers or malignancies
that begin in the epithelial cells, which are
the cells that make up the skin, and the
tissues that line various internal organs and
structures. Some of the most common
carcinomas affect the breast, lung, prostate,
and colon.
Leukimia is a group of blood cancers that
usually begin in the bone marrow and result
in high numbers of abnormal blood cells.
These blood cells are not fully developed
and are called blasts or leukemia cells.
Symptoms may include bleeding and
bruising, bone pain, fatigue, fever, and an
increased risk of infections.
Lymphoma is a group of blood and lymph
tumors that develop from lymphocytes (a
type of white blood cell). The name usually
refers to just the cancerous versions rather
than all such tumours.
Multiple myeloma, also known as myeloma,
is a type of bone marrow cancer. Bone
marrow is the spongy tissue at the centre of
some bones that produces the body's blood
cells.It's called multiple myeloma as the
cancer often affects several areas of the
body, such as the spine, skull, pelvis and
ribs.
Melanoma, also redundantly known as
malignant melanoma, is a type of skin
cancer that develops from the pigmentproducing cells known as melanocytes.
Melanomas typically occur in the skin, but
may rarely occur in the mouth, intestines, or
eye.
Brain and Spinal Cord Tumors refer to the
masses of uncontrolled cell growth within
the skull or the bony spinal column. Brain
and spinal cord form the central nervous
system or CNS. Tumors may develop in
these areas when the genes that regulate
cell growth and multiplication become
mutated or damaged.

Most hair loss during cancer treatment is
caused by chemotherapy. That's because
chemo targets rapidly growing cells, which
damages hair follicles and makes the hair
fall out.
