There’s good news for cancer patients: Treatments are becoming less invasive and taking less time.

Traditional treatments often include chemotherapy or radiation to kill cancer cells and shrink tumors. The treatments kill healthy cells as well as cancerous ones, and the side effects are legendary.


Surgery can be an option, too. Sometimes it’s all that’s needed, but many people have some combination of chemo, radiation and surgery. These treatments can span months, and patients have months more of recovery time.

Cancer treatment is now moving toward precision medicine that targets just the cancer.

For example, doctors are using focused radiation, after a lumpectomy, for women who have early stage breast cancer. With this procedure, radiation beams pinpoint the tumor from hundreds of different angles for a short period of time. Each beam itself is weak, but together, when they hit the tumor, the result is a higher dose of radiation.

Just five days

Dr. Julia White at the Ohio State University Comprehensive Cancer Center found focused radiation has the same positive results as full breast radiation. Plus, the partial radiation takes only five days.

White said, “The short five-day treatment is just as good as the whole breast irradiation [that lasts] for four to six weeks.”

Other treatments use the body’s own immune system. Dr. William Nelson at Johns Hopkins Medicine told VOA it’s clear that the immune system sees cancer cells as abnormal, “and if we unleash the immune system, it can attack and destroy the cancer cells.”

The American Cancer Society says immunotherapy has become an important part of treating some cancers, and that newer types of immune treatments, currently being studied, will affect how we treat cancer in the future.

Still another new treatment, genomic testing, involves testing the cancer cells to determine their genetic makeup.

Most cancers start because of genetic mutations, and each patient’s cancer is unique, just like his or her DNA. If doctors know the particular DNA, they can prescribe medicine that targets the mutated cells. Healthy cells are left alone.

Dr. Marcia Brose at the Abramson Cancer Center at the University of Pennsylvania specializes in this type of treatment. In a Skype interview with VOA, she said genomic testing and precision medicine targets cancer cells “at the very core of what made them a cancer to begin with, and that’s what precision medicine is really about.”

Few side effects

Brose said few patients have any side effects. If they do, she lowers the dose of the medication. It eliminates the side effect, and the treatment is still effective.

Because genomic testing is costly, Brose said, the biggest impact right now is for patients whose cancer keeps returning or spreads to other parts of the body. She doesn’t see it yet as a first-line treatment. But the results are outstanding.

Brose recalled treating a woman with a rare type of cancer called sarcoma. When they met, the patient was in a wheelchair and on oxygen. Brose said that three years after treatment, the woman is hiking with her kids.

Brose said that patients whose cancers aren’t responding to treatment should ask their doctors about genomic testing. It isn’t for everyone, but Brose and other cancer specialists think targeted therapy, immunotherapy or genomic testing and precision medicine are the future of cancer treatment. And one day, it will be the standard treatment worldwide. (VOA)

Savitribai Khanolkar, the designer of Param Vir Chakra

Eve Yvonne Maday de Maros, the woman who designed the Param Vir Chakra, was born in 1913 in Neuchatel, Switzerland. It was believed that she came to India to understand the country's culture and tradition.

India has been ranked 139 out of 149 countries in the list of UN World Happiness Report 2021.

By Aishwarya Jain

According to the World Happiness Report 2021 which was released by the UN Sustainable Development Solutions Network, Finland was once again crowned as the world's happiest country. India has been ranked 139 out of 149 countries in the list of UN World Happiness Report 2021. To make society happy, firstly it is really important to spread awareness on how it is okay to relax, chill and take a break. People tend to normalise overworking, which is so wrong. Of Course, we need a job to live and sustain ourselves but you shouldn't be working yourself to death, and the fact that this is seen as normal is really worrying. You spend more hours at work than you do awake at home, so if those hours are drenched in misery then sadness basically becomes the norm. A study from Gallup (2017) found that happier employees were more engaged, which resulted in improved customer relationships, and a 20 percent increase in sales.

Also, lowering down the crime level would act as a major factor towards a happy society. People who witness crimes, or come across evidence of a crime in their local area, can suffer anxiety and may feel demoralised or powerless. We should also teach them to stop judging people by materialistic things and accept everyone with all their flaws. Media plays an important role in making society happy because they have the power of reaching out to billions of people and helping them out through a solution-based approach.
