The 10 Deadliest Cancers And Why There’s No Cure
Any kind of cancer is awful. Here is information about the 10 deadliest cancers.
The dread and fear that can come with a cancer diagnosis have their roots in its killer nature: Cancer is the second most common cause of death in Americans after heart disease, according to the Centers for Disease Control and Prevention. Even when diagnosed early and attacked with the latest treatments, cancer still has the power to kill.
Worldwide, the three cancers that killed the most people in 2020 were lung cancer , colorectal cancer and liver cancer . But those aren’t the deadliest cancers, according to Rebecca Siegel, senior scientific director of surveillance research at the American Cancer Society .
The number of people a cancer kills each year depends on two factors: how many people have it and what percentage of people diagnosed with the cancer survive it , Siegel explained. The deadliest cancers are those with the lowest survival.
Cancer researchers determine survival with a measure called the 5-year relative survival. This is the percentage of people who are expected to survive the effects of a given cancer, excluding risks from other possible causes of death, for five years past a diagnosis, according to the Surveillance, Epidemiology, and End Results Program , a National Cancer Institute initiative that collects, compiles, analyzes and reports data and statistics on cancer cases nationwide.

Understanding Prostate Cancers Progression
To determine the appropriate treatment, doctors need to know how far the cancer has progressed, or its stage. A pathologist, the doctor trained in analyzing cells taken during a prostate biopsy, will provide two starting pointsthe cancers grade and Gleason score.
- Cancer grade: When the pathologist looks at prostate cancer cells, the most common type of cells will get a grade of 3 to 5. The area of cancer cells in the prostate will also be graded. The higher the grade, the more abnormal the cells.
- Gleason score: The two grades will be added together to get a Gleason score. This score tells doctors how likely the cancer is to grow and spread.
After a biopsy confirms prostate cancer, the patient may undergo additional tests to see whether it has spread through the blood or lymph nodes to other parts of the body. These tests are usually imaging studies and may include a bone scan, positron emission tomography scan or computed tomography scan.

Psa And Gleason Score
Two other important factors that doctors and specialists use to assess cancer cells are the prostate specific antigen and the Gleason score.
PSA levels: PSA is a protein that appears in higher levels in the bloodstream when there is a problem with the prostate. Normally, PSA levels in the blood are very low, and a test cannot detect them. However, in some circumstance, such as prostate cancer, PSA levels start to rise.
Screening for prostate cancer uses a blood test for PSA. If PSA levels are high, the doctor may recommend further tests to see if prostate cancer is present.
There are various other reasons why PSA levels may rise, including sexual stimulation or an infection.
The grade and Gleason score: Different types of cancer cell act differently. Some types, or grades, are more aggressive and can spread more easily. The Gleason score and grade are different measures, but they both reflect how likely it is that a tumor will spread, and how quickly it will do so. Either a biopsy or surgery can determine the types of cancer cells present in the prostate tissues.
Nearly 50% of males have a condition known as prostatic intraepithelial neoplasia by the time they are 50 years old. PIN is when there are changes in the cells that line the prostate gland.
High grade PIN is not cancer, but the cells can become cancerous in the future. For this reason, a doctor may recommend treatment to remove the cells.
What Are The Risk Factors
Age is the primary risk factor with prostate cancer mainly affecting men over fifty. Those with a family history of prostate cancer and black men are also at risk. In the UK, about 1 in 4 black men are diagnosed with prostate cancer and although the cause is still unknown, Professor Ros Eeles is currently undertaking a five-year study into the genetic risks of prostate cancer.

How Is Prostate Cancer Treated
Lorenzo asked his doctors about survival and side effects and talked to friends and family members before deciding on treatment. He shares his story in this blog post.
Different types of treatment are available for prostate cancer. You and your doctor will decide which treatment is right for you. Some common treatments are
- Expectant management. If your doctor thinks your prostate cancer is unlikely to grow quickly, he or she may recommend that you dont treat the cancer right away. Instead, you can choose to wait and see if you get symptoms in one of two ways:
- Active surveillance. Closely monitoring the prostate cancer by performing prostate specific antigen tests and prostate biopsies regularly, and treating the cancer only if it grows or causes symptoms.
- Watchful waiting. No tests are done. Your doctor treats any symptoms when they develop. This is usually recommended for men who are expected to live for 10 more years or less.
A Biopsy Is Done To Diagnose Prostate Cancer And Find Out The Grade Of The Cancer
A transrectal biopsy is used to diagnose prostate cancer. A transrectal biopsy is the removal of tissue from the prostate by inserting a thin needle through the rectum and into the prostate. This procedure may be done using transrectal ultrasound or transrectal MRI to help guide where samples of tissue are taken from. A pathologist views the tissue under a microscope to look for cancer cells.
Sometimes a biopsy is done using a sample of tissue that was removed during a transurethral resection of the prostate to treat benign prostatic hyperplasia.
If cancer is found, the pathologist will give the cancer a grade. The grade of the cancer describes how abnormal the cancer cells look under a microscope and how quickly the cancer is likely to grow and spread. The grade of the cancer is called the Gleason score.
To give the cancer a grade, the pathologist checks the prostate tissue samples to see how much the tumor tissue is like the normal prostate tissue and to find the two main cell patterns. The primary pattern describes the most common tissue pattern, and the secondary pattern describes the next most common pattern. Each pattern is given a grade from 3 to 5, with grade 3 looking the most like normal prostate tissue and grade 5 looking the most abnormal. The two grades are then added to get a Gleason score.

What Is My Outlook
Many men will want to know how successful their treatment is likely to be. This is sometimes called your outlook or prognosis. No one can tell you exactly what will happen, as it will depend on many things, such as the stage of your prostate cancer and how quickly it might grow, your age, and any other health problems. Speak to your doctor about your own situation.
Most localised prostate cancer is slow-growing and may not need treatment or shorten a mans life. For many men who have treatment for localised prostate cancer, the treatment will get rid of the cancer. For some men, treatment may be less successful and the cancer may come back. If this happens, you might need further treatment.

Can Diet Help Fight Prostate Cancer
Can adopting a healthier diet help fight prostate cancer? That’s a question men newly diagnosed with prostate cancer often ask their doctors.
Several studies have shown that in countries where men eat a typical “Western” diet containing a large amount of meat, the incidence of prostate cancer, especially aggressive prostate cancer, is higher than in countries where plant-based foods are a primary part of the diet. Unfortunately, these studies weren’t designed to prove cause and effect. So for now, definitive answers about prostate cancer and diet aren’t yet in although researchers are actively studying this topic.
Investigators launched a federally funded national study to see whether a diet that’s higher in plant-based foods and lower in animal-based foods than the typical Western diet would help control tumor growth in men with early-stage prostate cancer.
The Men’s Eating and Living study included men 50-80 years old who had small, low-grade tumors and who opted to have their condition followed closely rather than undergoing immediate treatment. The researchers randomly assigned participants to telephone counseling about how to achieve the dietary MEAL goals or to a control group that received standard dietary advice for Americans.
Here’s what the MEAL eating plan looks like:
Cancer May Spread From Where It Began To Other Parts Of The Body
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began and travel through the lymph system or blood.
- Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor in another part of the body.
- Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor in another part of the body.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if prostate cancer spreads to the bone, the cancer cells in the bone are actually prostate cancer cells. The disease is metastatic prostate cancer, not bone cancer.

Figure 1 Location Of The Prostate Gland
The prostate gland, about the size of a walnut, produces fluid that forms part of the semen that is ejaculated during sexual activity. The prostate is located adjacent to the rectum and just below the bladder, and wraps around the upper part of the urethra, which carries urine from the bladder out of the body.
This location creates challenges in both diagnosis and treatment. During a digital rectal exam, for example, a doctor is able to feel only the back portion of the prostate. If cancer has developed in the apex, base, or deep inside the prostate, it may not be palpable.
Surgeons and radiation oncologists also face challenges in eradicating a tumor without causing lasting damage to surrounding organs and structures. When removing a tumor from the breast or colon, a surgeon is able to remove enough surrounding tissue to ensure clean margins, meaning that all the cancer has been removed. But when treating prostate cancer, a comparable amount of tissue cannot be removed surgically or targeted. It takes a skilled surgeon and radiation oncologist to eradicate diseased tissue without harming portions of the rectum, bladder, and penis, thereby minimizing the likelihood of complications.
Its also important to understand the limits of current medical knowledge about prostate cancer.
Table 2 What Guides Treatment Recommendations
Both of the situations below involve men diagnosed with a tumor that is small in size , yet who may require quite different treatments, based on their PSA level and Gleason score. Of course, many men have clinical profiles that vary from these two extremes.
Clinical profile Low PSA
Low Gleason score
80% of men with this profile probably have locally confined disease.
It is likely that fewer than 3% will have evidence of cancer in lymph nodes.
Surgery, radiation, or active surveillance . High PSA
High Gleason score
5% of men with this profile probably have locally confined disease.
More than 20% probably have evidence of cancer in the lymph nodes.
Systemic therapy rather than surgery .
Radical prostatectomy . The surgeon removes the prostate and seminal vesicles . In some cases, pelvic lymph nodes are also sampled. This is most often performed through an abdominal incision abdominal surgery may also be done with a laparoscope. A third option is the perineal technique, involving an incision in the area between the scrotum and the anus . The most common side effects are
- impotence
- mild to severe incontinence .
External beam radiation therapy. After a CT scan constructs a three-dimensional picture of the prostate and seminal vesicles, the radiation oncologist directs rays of high-energy radiation at the prostate tumor and sometimes at nearby lymph nodes. The most common side effects are
- impotence
- mild to severe incontinence .
- impotence
- mild to severe incontinence .

How Is Stage Ii Prostate Cancer Treated
The treatment methods for stage III of prostate cancer include:
- External beam radiation along with hormone therapy
- External beam and brachytherapy with hormone therapy
- Radical prostatectomy may or may not be followed by radiation therapy
External beam radiation:
It is a type of radiation therapy, a treatment method that involves use of high beams of X rays to kill cancerous cells. In external beam radiation therapy, also called EBRT, beams of radiation are focused on the prostate gland from a machine outside the body and it is used to treat the early stages of cancer.
Brachytherapy:
Brachytherapy is a type of radiation therapy too. Also called seed implantation or interstitial radiation therapy, small radioactive pellets of the size of a grain of rice are placed directly inside the prostate gland. This treatment is used alone in patients in the early stages of cancer showing relatively slow growth. Otherwise, this is preferred in combination of other treatment methods.

Articles On Cancer Types
There are no guarantees when it comes to cancer recovery. But doctors have greater success finding and treating some types of the disease than others. Some are slowly starting to use another “C” word for cancer: “cure.”
Some experts don’t use that word, noting that you can never be sure that cancer will go away for good after treatment. They prefer to say “remission,” meaning there’s a chance the disease can return. But in general, a person who stays cancer-free 5 years after a diagnosis has better odds of recovery.
That benchmark doesn’t mean you canât die from cancer or even that you don’t still have it in your body, but it is a good sign.
Here are five cancers where there’s stronger hope for recovery.
