In the United States, cancer deaths have decreased by 33 percent since 1991, with an estimated 3.8 million lives saved, largely due to advances in early detection and treatment.
Still, 10 million people worldwide lost their lives to cancer in 2020. In what doctors call an "alarming trend," cancer diagnoses are rising among young people around the world.
Over the past three years, cancer has remained the leading cause of death in the world, more than corona.
"Symptoms of cancer can mimic those of many other diseases, so it can be difficult to tell them apart," Dr. Arif Kamal, chief medical officer of the American Cancer Society told CNN. "Signs include unexplained weight loss or gain, swelling or Lumps in the groin, neck, abdomen, or armpits and fever and night sweats," according to the National Cancer Institute. Bladder, bowel, skin, and neurological problems may be signs of cancer, such as changes in hearing and vision, seizures, headaches, and bleeding or bruising without Reason But most cancers don't cause pain at first, so it can't be relied on as a sign.
Some cancers are preventable.

"We tell patients that if they have symptoms that don't improve after a few weeks, they should see a doctor," Kamal said, "however, that doesn't mean the diagnosis will be cancer."
Instead of waiting for symptoms, the key to preventing cancer is prevention, along with tests to detect the disease in its early stages.
This is critical, experts say, because new cases of cancer are on the rise worldwide.
A surprising number of new diagnoses are found in people under the age of 50, according to a 2022 review of research conducted by scientists at Harvard University.

Cases of breast, colon, esophageal, gallbladder, kidney, liver, pancreas, prostate, stomach and thyroid cancers have increased among 50-, 40- and even 30-year-olds since the 1990s.
That's unusual for a disease that usually affects people over 60, Kamal said.
"Cancer is generally considered an age-related condition."
Aged cells experience decades of wear and tear from environmental toxins and less favorable lifestyle choices, making them prime candidates for cancerous mutation.
"We believed that it takes time for this to happen, but if someone is 35 when they develop cancer, the question is, 'What could have happened?'" asked Dr. Kamal.
What are the causes and how are they prevented?
No one knows for sure, but smoking, alcohol consumption, air pollution, obesity, physical inactivity and a diet that includes few fruits and vegetables are major risk factors for cancer, according to the World Health Organization.
"Increased consumption of processed or Westernized foods along with changes in lifestyle, environment and other factors may have contributed to such changes in exposure," the researchers wrote in their 2022 review. Kamal added.
"What you need is about 20 years, and then you start seeing stomach cancer and colon cancer, even at young ages."
So what is the best way to prevent?
First and foremost find out the family history.
In some types of cancer, this is a clarification that can save lives.
If your family member had cancer, for example in the digestive system, you will also be required to have a colonoscopy every few years and above a certain age.
Even when it comes to breast cancer, there are inquiries that can be made, including testing for the presence of the BRCA gene and more frequent testing by a breast surgeon and mammography at a younger age.
Another and no less important thing is to simply conduct screening tests recommended according to your age and make sure to do them on time.
These tests can save lives.
