milestone today. exactly 40 years ago, december 23, 1971, congress passed and president nixon signed the national cancer act. it was widely viewed as the start of this nation's war on cancer. tonight our chief science correspondent robert bazell with how things are going. >> reporter: terry minisian learned she had breast cancer in 2003. today she is just fine. >> i am doing better and looking better than i was to begin with. >> reporter: she's one of 12 million american cancer survivors. more than 1 in 20 adults. >> it could give some hope -- >> reporter: in 1971 when president bipartisan support announced a goal of defeating cancer, 3 million americans were dealing with a cancer diagnosis. in the decades after the national cancer act passed congress, the most important statistic, the death rate from cancer, actually shot up for men

and for women. since then it has come down, but is now only 11% lower for men and 6% lower for women than it was in 1971. the largest contributor to those changes in both directions was the tobacco use went way up and then started to come down. colonoscopies and other screening tools have lowered colon cancer rates while early detection and better treatments brought down breast cancer and prostate cancer rates. the war on cancer, which increased federal funding for cancer research from $200 million a year then to $5 billion a year now has brought an enormous scientific understanding, especially in human genetics. so why hasn't the death rate fallen faster? cancer is actually more than 150 diseases where cells grow out of control. many scientists say understanding and controlling cancer is a challenge almost as great as understanding all the

details of life itself. >> the cancer cell is a very complex, very sophisticated organism. and we have to learn a great deal more before we are ever going to actually change biology. >> reporter: experts see continued progress in this war, but no imminent victory. robert bazell, nbc news, new york. late word tonight from london that queen elizabeth's husband, prince philip, has been hospitalized after suffering chest pains. the 90-year-old duke underwent surgery to treat a blockeded coronary artery. he's resting comfortably. when we come back, the extraordinary kindness of strangers, paying it forward this holiday a season.

and the feats of strength. up next, making a difference for folks in new orleans, one house at a time. y at rest... while a body in motion tends to stay in motion. staying active can actually ease arthritis symptoms. but if you have arthritis, staying active can be difficult. prescription celebrex can help relieve arthritis pain so your body can stay in motion. because just one 200mg celebrex a day can provide 24 hour relief for many with arthritis pain and inflammation. plus, in clinical studies, celebrex is proven to improve daily physical function so moving is easier. and celebrex is not a narcotic. when it comes to relieving your arthritis pain, you and your doctor need to balance the benefits with the risks. all prescription nsaids, like celebrex, ibuprofen, naproxen, and meloxicam have the same cardiovascular warning. they all may increase the chance of heart attack or stroke, which can lead to death. this chance increases if you have heart disease or risk factors such as high blood pressure or when nsaids are taken for long periods. nsaids, including celebrex,

increase the chance of serious skin or allergic reactions or stomach and intestine problems, such as bleeding and ulcers, which can occur without warning and may cause death. patients also taking aspirin and the elderly are at increased risk for stomach bleeding and ulcers. do not take celebrex if you've had an asthma attack, hives, or other allergies to aspirin, nsaids or sulfonamides. get help right away if you have swelling of the face or throat, or trouble breathing. tell your doctor your medical history and find an arthritis treatment for you. visit celebrex.com and ask your doctor about celebrex. for a body in motion. nyqui tylenol: me, too. and cougnasal congestion.ers? visit celebrex.com and ask your doctor about celebrex. nyquil:what? tissue box (whispering): he said nasal congestion... nyquil: i heard him. anncr vo: tylenol cold multi-symptom nighttime
