are cancer survival rates going up?
For stage 2A lung cancer, between 36 and 46 out of every 100 people diagnosed (36% to 46%) will survive for 5 years or more with treatment. For stage 2B non small cell lung cancer, between 25 and 36 out of every 100 people diagnosed (25% to 36%) will survive for 5 years or more after they are diagnosed. 1 Women diagnosed with breast cancer that had spread to nearby skin or lymph nodes (regional breast cancer) had 10-year survival rates go up from 16.2% in 1944-54 to 74.1% by 1995-2004. lenetstan/Shutterstock. New cases of cancer among adults in California are declining, but rates of childhood cancers are increasing, according to a new study by a statewide health organization. The report, by the California HealthCare Foundation, also shows that cancer survival rates are improving for kids and adults. Researchers and oncologists point to several trends, such as falling smoking rates, that explain the declines in new adult cancer cases in the last 20 years. 2 out of 3 people with small cell lung cancer already have extensive disease at the time of diagnosis. Unfortunately the survival rate is very low. With treatment, fewer than 5 out of every 100 people (5%) will survive for 5 years or more after diagnosis. The Lung Cancer Staging Project used the TNM staging system to give the following statistics about survival based on the stage found by scans and tests. Since 1989, the rate of new cancers in California adults has fallen from 456 per 100,000 residents to 413, about a 9 percent decline, according to the foundation report, released last week. Rates among children inched up, though, from 15.4 cases per 100,000 children to 17.8, an increase of about 15.6 percent. 1 Women diagnosed with breast cancer that had spread to other parts of the body away from the breast (metastatic breast cancer) had 10-year survival rates go up from 3.3% in 1944-54 to 22.2% by 1995-2004. It can seem illogical for stage 3B cancer to have 5 year survival rates from 7% to 9% and stage 4 from 2% to 13%. This is because the staging system only looks at the extent of the cancer. 1 Women diagnosed with breast cancer that hadn't spread beyond the breast (local breast cancer) had 10-year survival rates go up from 55.0% in 1944-54 to 86.1% by 1995-2004. As you might expect, the survival statistics fall with more advanced stages of lung cancer. Again, stage 3 is divided into stage 3A and stage 3B. For stage 3A non small cell lung cancer, between 19 and 24 out of every 100 people diagnosed (19% to 24%) will survive for 5 years or more after they are diagnosed. Ongoing studies are examining genetic factors, immune system development and chemicals found in household dust, she said. For both children and adults, though, cancer survival rates improved from 1989 to 2009. For adults, mortality rates fell by 22 percent, with 158 per 100,000 people dying of cancer in 2009.
