1. Cancer Treatment

2. What is Cancer
In simple terms, cancer refers to an
abnormal growth of cells in the body. This
abnormal growth of cells can take place in
any part of the body, including, lungs,
breasts, kidneys, bladder, colon, skin and
prostate. Cancer cells or tumours can
either restrict themselves to their place of
origin (benign tumour) or travel to other
parts of the body (malignant tumour).
The signs and symptoms of cancer
depend on the type, extent and severity
of the condition.

3. All cells that undergo unregulated growth to form a mass of cell or lump
(tumours) are characterised as cancer when they show the following signs:
• Continuous cell growth without any signalling
• Continuous cell growth even under inhibition signalling
• Limitless cell division
• Programmed cell death evasion
• Blood vessel constriction
• Metastases and invasion of other tissues
Signs of cancer

4. Symptoms of cancer, which depends on the type of cancer, start to appear when
the mass of cells starts to multiply or forms an ulcer. Cancer symptoms can
“imitate” the symptoms caused by anther condition that the cancer patient
already has. Symptoms of cancer can be divided into the following three
categories:
• Systemic symptoms
• Local symptoms
• Metastasis
Symptoms of cancer

5. Cancer occurs when the cells divide uncontrollably and there is no cell death. There
are a number of reasons that can trigger this uncontrolled growth of cells. Typically,
normal cells get converted into cancerous cells when their DNA gets damaged and
there is either no repair of the DNA or natural cell death.
However, the cancerous cells continue to divide and give rise a cascade of other
abnormal cells, leading to the formation of a mass of cells. This damage to the DNA
can be triggered by a number of factors, which can be categorized into
environmental factors or genetic factors. It is estimated that 90 to 95 percent of
cancer cases reported each year are because of an exposure to environmental
factors (radiation, exposure to pathogens, tobacco, and carcinogens).
Causes of Cancer

6. Diagnosis of Cancer
The cancer diagnosis may be conducted as soon as the patient shows specific
symptoms or if preventive screening tests for cancer turn out to be positive. The
doctor may first ask questions about family and personal history before conducting
a physical exam and lab tests (blood, urine, body fluids). Based on the preliminary
findings, one or a combination of following imaging tests may be conducted to
make a diagnosis of cancer:
• Computed Tomography (CT) Scan
• Nuclear Scans
• Ultrasound
• Magnetic Resonance Imaging (MRI)
• X-ray
• Positron Emission Tomography (PET) Scan

7. Treatment of Cancer
There are different types of cancer treatment available, the choice of which may
depend on the type of cancer, the health status of the patient, age, stage of cancer
and the severity of symptoms. Most often, either one or a combination of
following procedures to treat cancer are opted by the doctors based on their
diagnosis. Few of the treatment options for cancer are available here:
• Surgery
• Radiation Therapy
• Chemotherapy
• Immunotherapy
• Hormone therapy
• Gene therapy
