Embrace Technology-Driven Medical Techniques to Prevent and Treat Cancers

Due to the rise of cancer cases, India should leverage technology-driven medical techniques to prevent health catastrophes in an effective and affordable manner, warns a leading oncologist. The other three trends are use of genomic profiling, evolution of gene editing technologies, and next generation of immunotherapies and CAR T cell therapies, said Abraham, in an article in the annual publication of a leading vernacular media house in the state.

Trends that Reshape the Future of Cancer Care

"Digital technology, information technology, and telehealth will narrow the gap between patients and specialists. This will also potentially enhance the availability of expert care in remote parts of our country, including rural settings where the majority of our population lives," says the reputed oncologist.

"India's biggest challenge will be how to make it affordable and accessible for millions of its people when these technologies continue to revolutionize cancer care," said Abraham.

As per the Globocan estimates, the cancer burden worldwide is expected to be 28.4 million cases in 2040, a 47 percent rise from 2020, due to demographic changes.

This may escalate due to increasing risk factors associated with globalization and a growing economy.

An estimated 19.3 million new cancer cases and almost 10.0 million cancer deaths occurred across the world in 2020. According to the report, female breast cancer has surpassed lung cancer as the most commonly diagnosed cancer, while lung cancer remains the leading cause of cancer death, with an estimated 1.8 million deaths (18 percent), followed by colorectal (9.4 percent), liver (8.3 percent), stomach (7.7 percent), and female breast (6.9 percent) cancers.

Abraham holds that cancer vaccines are an exciting research area having the potential to immunize people against various cancers. Researchers have developed amazingly successful mRNA COVID-19 vaccines. The fact is that mRNA-based cancer treatment vaccines have been tested in small trials for more than a decade, with some promising early results.

"Currently at Cleveland Clinic, our team is doing a clinical trial testing cancer vaccine in high-risk breast cancer," he said.

Highlighting the role of cutting-edge technologies, he says computers using Artificial Intelligence (AI) can recognize variations in pattern from normal to abnormal in the biopsy much more accurately than the human eye. These technologies will require radiologists and pathologists to be more efficient and accurate.

Genetic profiling or testing at an early age to detect the abnormal gene can find breast and colon cancers in their earliest stages.

Noting that scans, mammograms, colonoscopy or a pap smear are currently used for cancer diagnosis, Abraham says by the time the tumor is detected, it can be too late.

"Hence, the treatment needs to be very aggressive. The emerging liquid biopsy technologies will help detect cancer from a drop of blood, before it can be detected by a scan or it manifests as a lump or ulceration."

Abraham has a word of caution, too. "When we develop novel technologies to prevent and treat cancer, we can't focus on cancer prevention. Most common causes of cancers are still tobacco, alcohol, diet, and infections. Policies for tobacco and alcohol control have to be a national priority," said the oncologist.
