Is the rate of cancers increasing or decreasing?


Actually, the rate at which cancer occurs in the population has changed little in the past 40 years.  The overall number of cases continues to increase because the population is growing and also getting older, and cancer is largely a disease of aging.  As people get older, more cases of cancer will occur. However, the cancer death rate has dropped by 23% since 1991, translating to 1.7 million fewer deaths through 2012, according to the American Cancer Society.  This is largely because of early detection, better treatment, and fewer people are smoking tobacco, the culprit in most lung cancers and a contributor to several other types.  So cancer is probably not occurring at a greater rate, it’s just that there are more people who are more likely to develop cancer because of their age, but we are better able to detect and treat those cancers in many cases.

KIDS AND PORNOGRAPHY - HOW TO STOP THEM Do you know what your teenager/younger one is doing on that data enabled phone or iPad??* Don't be caught unaware. Pornography is available with just one click. How about social media? Do you have any control over how much time they spend on it when they should be studying or sleeping? I am sure you worry about these things even though you realize that they need these devices as a means of communication and even learning. But as good parents, we must protect the minds of our teenagers and children. I thought it was a joke when my pastor's wife told me that there is a mobile application that I can download, just like I downloaded WhatsApp.  I did not believe it could actually protect my son until I tried it out myself. I have visited www.mindguard.com.ng and I have downloaded the parent app on my phone and the digital coach on my child's phone so that I can protect him from the dangers associated with the internet without...

WHAT A GREAT STORY *This is a great story. Take a moment to read it; I Pray it will make your day* A wealthy man and his son loved to collect rare works of art. They had everything in their collection, from Picasso to Raphael. They would often sit together and admire the great works of art.. When the Vietnam conflict broke out, the son went to war. He was very courageous and died in battle while rescuing another soldier. The father was notified and grieved deeply for his only son. About a month later, just before Christmas, There was a knock at the door. A young man stood at the door with a large package in his hands.. He said, 'Sir, you don't know me, but I am the soldier for whom your son gave his life. He saved many lives that day, and he was carrying me to safety when a bullet struck him in the heart and he died instantly... He often talked about you, and your love for art.' The young man held out this package. 'I know this isn't much. I'm...

The importance of Giving! As you probably recall, the Dead Sea is really a Lake, not a sea. It’s so high in salt content that the human body can float easily. The salt in the Dead Sea is as high as 35% - almost 10 times the normal ocean water. And all that saltiness has meant that there is no life at all in the Dead Sea. And hence the name: Dead Sea. The other Sea is the Sea of Galilee. It happens that the Sea of Galilee is just north of the Dead Sea. Both the Sea of Galilee and the Dead Sea receive their water from river Jordan. And yet, they are very, very different. Unlike the Dead Sea, the Sea of Galilee is pretty, resplendent with rich, colourful marine life. Same region, same source of water, and yet while one sea is full of life, the other is dead. How come? Here’s apparently why. The River Jordan flows into the Sea of Galilee and then flows out. The water simply passes through the Sea of Galilee in and then out - and that keeps the sea healthy and vibrant, teemi...
