CA: Latest Cancer Statistics: U.S. Cancer Death Rates Down 32% From Peak, Lung Cancer Survival Rates Improve, Breast Cancer Incidences Rise Slowly

Each year the American Cancer Society (ACS) estimates the number of new cancer cases and deaths in the United States and compiles the latest data on population-based cancer incidence and outcomes

In 2022, the latest research report (incidence data up to 2018, mortality data up to 2019) was published on January 12 in the "Divine Journal" CA: A Cancer Journal for Clinicians with an impact factor of 508.

The risk of dying from cancer in the U.

Cancer remains the second most common cause of death in the United States after heart disease

By gender, prostate, lung and bronchial cancer (hereafter referred to as lung cancer) andColorectal cancer will account for almost half (48%) of all cases in men in 2022, with prostate cancer alone accounting for 27% of diagnoses

Estimated new cases and deaths by sex in the United States in 2022 for the top ten major cancer types

Number of cancer deaths averted for U.

From 2015 to 2019, the risk of dying from cancer decreased by about 2% per year, compared with 1% per year in the 1990s

The researchers note that success in reducing cancer mortality requires more investment in two equally important areas: 1) cancer research that expands knowledge and advances better treatment options; 2) ensures successful, targeted Cancer control interventions can be applied more broadly and equitably to all populations

Advances in early diagnosis of lung cancer

The outlook for lung cancer at all stages of the disease is brighter than ever

Incidence trends of different stages of lung cancer diagnosis in the United States from 2004 to 2018

The improvement in survival is largely due to improvements in tests to diagnose lung cancer, video-assisted thoracoscopic surgery (VATS), updates to pathological staging, and drugs targeting the most common genetic mutations in lung cancer

Here are some other statistics about lung cancer :

• Lung cancer still kills more than 350 people every day, the most of any type of cancer, more than breast, prostate and pancreatic cancers combined
  .
  It is responsible for 2.
  5 times as many deaths as colorectal cancer, the second leading cause of cancer death in the United States
  .
  

• Eight out of 10 (81%) of lung cancer deaths in 2022 are expected to be caused by smoking
  .
  Both the amount and duration of smoking increase the risk of dying from lung cancer
  .
  People who smoke are 25 times more likely to develop lung cancer than those who never smoke
  .
  

• Secondhand smoke is responsible for nearly 3% of new lung cancer diagnoses
  .
  In 2022, secondhand smoke is expected to cause about 3% of these deaths
  .
  

• After smoking, the next leading cause of lung cancer is exposure to radon
  .
  Radon gas is released from the soil and accumulates indoors
  .
  

• If non-smoking-related deaths from lung cancer were classified separately, it would rank eighth among the causes of cancer deaths
  .

From the mid-1990s to the mid-2010s, the risk of dying from prostate cancer decreased by about 50% due to improved treatment and screening with prostate-specific antigen (PSA) testing, which helps detect cancer at an early stage ( only in the prostate)
.
But in recent years, the risk of dying from prostate cancer has dropped by only 0.
6% per year
.
The reason for the slow progress may be related to changes in cancer screening guidelines
.

Although screening helps reduce mortality, there is growing evidence that PSA testing is doing undue harm through overdiagnosis and overtreatment of prostate cancer
.
As a result, the U.
S.
Preventive Services Task Force (USPSTF) changed their screening guidelines
.
In 2008, the USPSTF recommended not routine PSA screening for men 75 years of age and older, and in 2012, all men were not tested for PSA
.

Initially, after PSA testing was reduced, prostate cancer diagnoses dropped rapidly
.
But from 2014 to 2018, the incidence of localized stage disease (no evidence that the cancer has spread outside the prostate) remained stable, while the incidence of regional stage disease (cancer spread to structures or lymph nodes near the prostate) increased by 4 per year.
%, the incidence of distal-stage disease (cancer that has spread to distant parts of the body, such as the brain, bones, liver) is rising by 6% per year
.
As a result, the proportion of patients diagnosed with distal-stage prostate cancer has more than doubled in the past 10 years, from 3.
9% to 8.
2%

Controversy remains about the underutilized potential of PSA testing to "reduce prostate cancer mortality through early detection," the ACS researchers noted
.

Since the mid-2000s, the incidence of breast cancer in women has been increasing at a slow rate of about 0.
5% per year
.
The rise in diagnoses is partly due to more women being obese, having fewer children, or having their first child after age 30
.
The rate of decline in breast cancer mortality has slowed in recent years, which may be related to rising incidence and unchanged mammography rates
.

Cancer is the second most common cause of death in children ages 1 to 14 in the United States
.
Accidents are the most common cause
.

• In 2022, an estimated 10,470 children will be diagnosed with cancer and 1,050 children will die of cancer
  .
  

• Although childhood cancer rates have risen since the mid-1970s, childhood cancer mortality rates have declined by 71 percent since 1970, largely due to improved treatment and more children participating in clinical trials
  .
  

• Leukemia remains the most common childhood cancer, accounting for 28% of all cancers in children
  .
  From 1970 to 2019, the death rate from leukemia dropped by 84%
  .
  

• Brain and other nervous system tumors are the second most common type of childhood cancer, accounting for 26% of all childhood cancers

• In 2022, an estimated 5,480 teens will be diagnosed with cancer and 550 will die of cancer
  .
  

• Similar to children, teenage cancer rates have risen slightly over the decades, while cancer death rates have fallen by 61% from 1970 to 2019
  .
  

• Brain and other nervous system tumors are the most common type of juvenile cancer, accounting for about 21% of juvenile cancers, followed by lymphoma (19%)

For complex reasons, advances in cancer treatment in adolescents have lagged behind that in children
.
Reasons include low enrollment in clinical trials, differences in tumor biology and treatment regimens, and treatment tolerance and compliance
.

• According to the ACS study, at least 42% of projected new cancers are avoidable
  .
  This includes 19% of cancers caused by smoking and at least 18% caused by a combination of excess weight, alcoholism, malnutrition and physical inactivity
  .
  

• A new combination immunotherapy for metastatic melanoma, a historically difficult cancer to treat, has become a game-changer
  .
  In 2004, only 15 out of 100 patients diagnosed with distal-stage melanoma were still alive 5 years later
  .
  For patients diagnosed between 2011 and 2017, thanks to these new treatments, the number of patients surviving five years later doubled—30 out of 100
  .
  

• The incidence of liver cancer, one of the deadliest cancers, has finally stabilized
  .
  Just a few years ago, it was the fastest growing cancer
