“Cancer: An old disease with a new face”
By CHIOMA OBINNA
Nigeria is facing a double burden of infectious and chronic diseases. One of such dieseases is Cancer.
Today in Nigeria, cancer is seen as a death sentence. Before now, cancer is believed to be the disease of the white man but today, the whole story has taken another dimension as the incidences of cancer is fast gaining ground among Nigerians. Presently, cancer is among the leading cause of deaths in Nigeria. It is now obvious that the burden of cancer in Nigeria is appreciable.
In the last few years, so many prominent Nigerians have lost their lives to cancer, the latest is the Managing Director / Chief Executive Officer of Guaranty Trust Bank, Mr. Tayo Aderinokun.
No one needs a soothsayer to tell that cancer and its destructive effects is very much in the country.
According to the World Health Organisation (WHO) there are an estimated 100,000 new cancer cases in the country annually, although observers believe the figure could become as high as 500,000 new cases each year.
More worrisome is that experts have predicated that by 2020, the number of cancer patients in Nigeria is going to rise from 24 million to 42 million as speculated 21 years ago. It is also feared that by same 2020, death rates from cancer in Nigerian males and females may reach 72.7/100,000 and 76/100,000 respectively.
Cancer is a class of diseases in which a group of cells display uncontrolled growth, invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis, or spreading to other locations in the body via lymph or blood. There are various types of cancer, cervical, ovarian, breast, lung, cancer of the blood, and prostrate cancers, among others. However, the most common type of cancer in Nigeria today are breast cancer, cervical and ovarian.
There are two major causes of cancer; environmental factor and others caused by hereditary genetic. Some of the common environmental factors leading to cancer as indicated include: tobacco, bad dieting, especially calories, infections, radiation, lack of physical activity, and environmental pollutants. These environmental factors, according to experts cause or enhance abnormalities in the genetic material of cells.
Although, cancer has been described as a killer disease, experts say when detected early, patients diagnosed with these cancers may be cured.Unfortunately, the health seeking behaviour of Nigerians has continued to hinder successful treatment of cancer. According to the National Coodinator, National Cancer Prevention Programme (NCPP), Dr. Kin J- Egwuonwu, cancer is both preventable and curable and early detection can increase the number of survivors.

What's amazing here is that this is the first time we have spotted one this size so many days in advance - and if it were on a collision course we would have been able to predict accurately the impact point (likely the South Pacific Ocean) several days

String theorists describe the physics of black holes in five-dimensional spacetime. They found that these five-dimensional objects provide a good approximation of the quark-gluon plasma in one fewer dimension, a relationship similar to the one between
ONE DIMENSIONAL ELASTIC COLLISIONS | TECHZZ
Consider a simple system of two spheres which are smooth and non rotating moving along the line joining their centres. They undergo head-on collision and move along the same straight line after collision. These bodies exert forces on each other during the collision. The forces are along the initial line of motion, so that the final motion is also along the same line in the same direction.
