Cancer Survival Analysis01:21

Cancer Survival Analysis

855
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Cancer Prevention

8.7K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Targeted Cancer Therapies

9.2K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

What is Cancer?

16.0K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Area of Science:

  • Oncology
  • Public Health
  • Epidemiology

Background:

  • Cancer represents a significant global health burden, with increasing incidence due to population aging and lifestyle changes.
  • Cancer burden is shifting towards less developed countries, accounting for a majority of cases and deaths.
  • In 2012, 14.1 million new cancer cases and 8.2 million deaths occurred globally.

Purpose of the Study:

  • To analyze global cancer statistics and trends.
  • To identify leading causes of cancer death by region and sex.
  • To highlight the impact of risk factors and the potential for prevention.

Main Methods:

  • Utilized GLOBOCAN estimates for global cancer data analysis.
  • Examined cancer incidence and mortality rates across developed and less developed countries.
  • Assessed the association between risk factors and leading cancer types.

Main Results:

  • Lung cancer is the leading cause of cancer death for males globally and females in developed countries.
  • Breast cancer leads female cancer deaths in less developed countries; colorectal, prostate, liver, stomach, and cervical cancers are also significant.
  • Despite higher incidence in developed nations, mortality rates show smaller disparities, indicating differences in detection and treatment.

Conclusions:

  • A substantial proportion of cancer cases and deaths are preventable.
  • Effective prevention measures include tobacco control, vaccination, and early detection tests.
  • Addressing risk factors and improving access to care are crucial for reducing the global cancer burden.
