Cancer is a relentless disease that touches lives far and wide. It is an illness that affects not just individuals but entire communities. Its impact is profound, challenging the physical and emotional well-being of cancer patients and their loved ones.
According to the WHO (World Health Organization), cancer is one of the leading causes of death worldwide. As of 2021, the approximate global incidence of cancer was over 19 million new cancer cases diagnosed annually.
Amidst the struggle, Genomics emerges as a beacon of hope. Genomics is a revolutionary force, unveiling the secrets of cancer on a genetic level. It is the study of an organism’s complete set of genes, known as its genome.
“Genomics is like reading the instruction manual for an organism,” explains Dr. Sridhar PS, a renowned radiation oncologist in India. “It’s the study of all the genes in our bodies, which hold the code for how we work. Whereas, Cyberknife treatment in India amplifies precision in targeting cancer cells with cutting-edge technology.”

Genomics and genetics may sound similar, but they have distinct roles.
Are you curious to learn more about these differences? Please get in touch with Dr. Sridhar PS. He is constantly researching factors impacting our health and the role of genomics in cancer treatment.
Read on as we try to shed light on the fundamentals of DNA and genes in the world of cancer.
Understanding the fundamental aspects of DNA and genes is very important in oncology. DNA serves as the detailed blueprint for our biological processes.
“Think of it as a long, twisted ladder made up of building blocks called nucleotides,” says Dr. Sridhar PS, an expert in DNA therapy for cancer. “Genes are like chapters in this manual, each containing specific instructions for different bodily functions.”
Cancer occurs when something goes wrong with these instructions. Mutations or gene changes can
cause cells to grow uncontrollably, leading to cancerous growth. It’s like a typo in the manual that makes the cells disregard the “stop growing” command.
“Genes related to cancer are often compared to “on” and “off” switches,” explains Dr. Sridhar. “Mutations can turn on genes that promote cell growth and turn off genes that prevent it. This imbalance results in the formation of tumors. If left unchecked, these tumors can spread throughout the body.”
Dr. Sridhar is a cancer expert known for effective cancer care, including prostate cancer treatment in
Genetic mutations are like the fingerprints of cancer. Come, let’s delve into some common genetic mutations associated with different forms of this complex disease.
Cancer is a complex disease with various genetic alterations. The specific mutations involved can vary even within the same type of cancer.
Some common genetic mutations associated with various types of cancer are:
Genetic Mutations Cancers
BRCA1 and BRCA2 Breast and ovarian cancers
EGFR and ALK NSCLC (Non-small cell lung cancer)
APC and KRAS Colorectal Cancer
PTEN and BRCA2 Prostate Cancer
KRAS Pancreatic Cancer
RET and BRAF Thyroid Cancer
BCR-ABL Fusion Chronic Myeloid Leukemia
TP53 Hematologic Cancers
KIT and PDGFRA Gastrointestinal Stromal Tumor
FGFR3 and TP53 Bladder Cancer

Understanding genetic mutations is essential for developing targeted therapies and personalized treatment plans.
The most common genomic-based therapies and treatment options in cancer include:
Targeted therapies focus on specific molecules or pathways responsible for cancer growth. Doctors identify genetic mutations within tumors. They then prescribe targeted drugs to inhibit these abnormalities, minimizing harm to healthy cells.
Immunotherapy harnesses the body’s immune system to fight cancer. Genomic profiling helps identify potential immunotherapy candidates by determining whether specific genetic markers exist. This approach enables the immune system to recognize and attack cancer cells effectively.
In his dedication to helping people battle cancer, Dr. Sridhar is constantly studying and analyzing genetic information. This includes understanding the complexities of:
He is among the preferred oncologists for people seeking advanced cancer treatments, including lung cancer treatment in India.

Genomics has ushered in a new era of cancer treatment, offering numerous advantages, like:
“Incorporating genomics into cancer care represents a significant leap forward,” says Dr. Sridhar PS, an expert in genomics and cancer treatment. “It promises improved patient outcomes and a brighter future in the fight against cancer.”
Let’s see the potential risks of genomics in cancer treatment – decoding complexities for safer advancements.
Genomics offers promising benefits in cancer treatment. However, there are important risks and considerations to keep in mind:
“Tumor genomics aims to understand the unique genomic characteristics of tumors,” says Dr Sridhar. “It can vary widely between cancer types and among individuals with the same type of cancer.”

Q. What is genomic testing for cancer?
Genomic testing for cancer involves analyzing a patient’s DNA. This helps to identify genetic mutations or alterations that may contribute to cancer development or influence treatment decisions.
Q. What are cancer genetics and genomics?
These terms refer to the study of genetic factors and genomic changes that play a role in cancer development, progression, and treatment.
Q. How is DNA used in cancer therapy?
DNA is used in cancer through gene therapy, where specific genes are modified or introduced to treat cancer. DNA-based treatments aim to target and control cancerous cells.
Q. How is genomics used in cancer?
Genomics is used in cancer research and clinical practice in various ways. They include:
Q. Will genomics cure cancer?
While genomics has dramatically advanced our understanding of cancer, it may not “cure” cancer alone. Genomic information is crucial for developing targeted therapies. However, curing cancer requires a combination of treatments tailored to individual cases.
