Lung Cancer Breast Cancer for Diagnosis No. 1 in the World

Women’s breast cancer is a jump-frogged lung cancer, now accounting for the largest studies of cancer worldwide – and the situation is likely to worsen in the coming decades.

In a report published on 4 February in CA: Cancer Journal for Clinicians, called “Global Cancer Statistics 2020,” the American Cancer Society (ACS) and the International Agency for Research on Cancer (IARC) shared their findings based on data from the Global Cancer Observatory.

Based on their analysis, 19.3 million new cancer cases were diagnosed in 2020, 2.3 million – 11.7 percent – of which were female breast cancers. In fact, it is now the No. 1 cancer identified in 159 of 185 countries included in the report.

“Overall, the burden of cancer incidence and mortality is growing rapidly around the world; this reflects both the age and growth of the population, as well as changes in the frequency and circulation of the main risk factors for cancer, many of which are associated with socio-economic development, ”said the lead team ACS Science Hyuna Sung, Ph.D. D.

Although their assessment concluded that female breast cancer is now the most common diagnosis, it is still fifth in terms of cancer mortality. And, women in changing countries – those moving from centrally designed economies to free market structures – suffer the most mortality, the team said. The number of women dying from breast cancer in changing countries is 17 percent higher than elsewhere, the team said.

Managing the causes of cancer deaths

The incidence rate is rising in countries where the rate has been historically low, including areas in South America, Africa and Asia. High-income countries, such as Japan and South Korea, are also affected. Cultural changes in these areas may have contributed to these increases, the team said.

“Dramatic changes in lifestyle, sociocultural, and built environments caused by growing economies and rising proportions of women in industrial workers have affected the frequency of breast cancer risk factors – deprivation and fewer children, increased levels of body weight and physical inactivity, ”the team said,“ and have led to a convergence towards the image of western risk factors. reduction of international gaps in breast cancer morbidity. ”

Top five cancer case sites for 2020

As previously mentioned, breast cancer mortality rates are higher in transition countries although the incidence rate is 88 percent higher in transition countries. Late detection may be responsible, Sung said.

“As the adverse outcome in these countries is largely due to late demonstration, there is an urgent need for efforts to encourage early detection, followed by timely and appropriate treatment, through the implementation of guidelines based on evidence and resources, ”said Sung.

Unfortunately, the team said, they do not see a future turnaround. In fact, over the next two decades, they anticipate that the cancer incidence will only grow. In their report, they project that there will be 28.4 million new cancer cases worldwide in 2040 – an increase of 47 percent from 2020. And, the countries that are moving up will see a relative increase higher compared to those countries that have already moved – 64 percent-to-95 percent compared to 32 percent-to-56 percent, respectively.

As a result, healthcare and treatment need to redouble their cancer prevention efforts to stop the tide, the team said.

“The burden of cancer incidence and mortality is growing rapidly around the world and reflects both the age and growth of the population, as well as changes in the incidence and circulation of the main risk factors for cancer, and many of these are related to socio-economic development, ”said senior author Freddie Bray, BSc (Hons), MSc, Ph.D., head of the IARC department of cancer research. “Immunological and therapeutic interventions are effective and sensitive to relevant resources for cancer diagnosis. Unique integration in health planning can reduce the global burden of cancer and reduce the evidence of cancer inequalities between transition and transition countries seen today. ”
