In 2020, around the globe, an estimated 18.1 million new cases of cancer were diagnosed, excluding non-melanoma skin cancer. This signifies that approximately one out of every six individuals will receive a cancer diagnosis at some point in their lifetime.

Regarding mortality, in the same year, roughly 10 million deaths occurred globally due to cancer. This translates to nearly one in six deaths worldwide being attributed to this disease. These statistics underscore the significant impact of cancer on a global scale. 

Unfortunately, the burden of cancer is expected to grow in the coming decades due to population growth and ageing. The World Health Organization estimates that by 2040, the number of new cancer cases will reach 28 million per year.

There is a huge need for oncologists, especially since survival rates have increased. People are noticing the positive results of preventive and corrective cancer care. This encourages more cancer patients to come out and seek healthcare or motivates more people to get screened for it.

The demand for oncologists is a complex and urgent global challenge. Addressing this gap requires coordinated efforts from governments, medical institutions, and healthcare professionals to ensure equitable access to quality cancer care for everyone.

Let's take a look at some of the best oncologists in the world.

Let's take a look at what you should consider while choosing your oncologist.

How to Choose the Best Oncologists in the World?

After someone has been diagnosed with cancer, it is important to choose a doctor for treatment. You can continue to visit the doctor who diagnosed you with cancer or switch to another expert for second opinion. 

Choosing an oncologist from a list of a few names can be difficult. During this difficult moment, you may feel you don't know how to choose from the various options. 

  • Research Credentials: Look for oncologists with impressive academic backgrounds, board certifications, and affiliations with renowned medical institutions.
  • Specialization: Consider specialists in your specific type of cancer, as they often have more expertise in diagnosis and treatment.
  • Experience: Evaluate their years of experience and patient success stories, particularly with cases similar to yours.
  • Referrals: Seek recommendations from trusted sources, including primary care physicians, friends, and family who have had positive experiences.
  • Hospital Affiliation: Check if the oncologist is associated with a reputable hospital or cancer center known for its advanced treatments and technology.
  • Communication Skills: Assess their ability to communicate complex medical information in a clear and empathetic manner.
  • Treatment Options: Inquire about the range of treatment options they offer, including clinical trials and innovative therapies.

These world renowned oncologists use some of the newest technologies while treating their patients. 

Let's take a look at what technologies these oncologists are offering.

What Latest Technologies Do Oncologists Worldwide Use?

  • CRISPR gene editing: CRISPR is a gene editing technology that can be used to target and modify specific genes. Oncologists are exploring how CRISPR could be used to develop new cancer treatments, such as gene therapy and cancer vaccines.
  • Artificial intelligence (AI): AI is being used to develop new ways to diagnose cancer, predict cancer risk, and personalize cancer treatment. For example, AI is being used to analyze medical images, such as MRI scans and CT scans, to identify cancer cells and predict how patients will respond to different treatments.
  • Liquid biopsies: Liquid biopsies are blood tests that can be used to detect cancer cells or cancer biomarkers in the bloodstream. Liquid biopsies are less invasive than traditional biopsies and can be used to monitor patients for cancer recurrence.
  • Precision medicine: Precision medicine is a personalized approach to cancer treatment that takes into account the specific genetic profile of a patient's tumour. Precision medicine allows oncologists to select the most effective treatments for each patient, based on their individual tumor characteristics.
  • Immunotherapy: Immunotherapy is a new type of cancer treatment that harnesses the body's immune system to fight cancer cells. Immunotherapy is effective in treating a variety of cancers, including lung cancer, melanoma, and colorectal cancer.
  • Robotic surgery: Robotic surgery is a minimally invasive surgical technique that allows oncologists to perform complex surgeries with greater precision and accuracy.

This form of cancer causes symptoms such as jaundice, weight loss, and belly pain. It starts when cells near the ampulla of Vater begin growing out of control. Treatment typically involves surgery followed by chemotherapy. You must collaborate closely with her physician to determine the most effective course of action for your mother. Be strong and be there for her during this difficult time.

Does cancer come back in everyone who is cured after treatment?

Male | 22

When an individual undergoes treatment and the disease fades away, it’s a relief. Nonetheless, there are times when it recurs after going into remission. It is contingent on the kind of malignancy one has as well as the method used for healing it. Signs that can indicate its reoccurrence may be similar to those experienced during the first onset such as unexplained weight loss, fatigue, or formation of new masses. To avoid its resurgence, you need to keep seeing your doctor for regular checkups besides living healthily.

Male | 64

When you have adenocarcinoma, you must stick to the treatment plan your doctor gives you. Chemotherapy is used often for treating this type of cancer. Just try to follow the treatment schedule, eat well, and get enough rest.
