100 Questions & Answers About Lung Cancer |
It is now applied to cancerous tumors because the enlarged veins resembled the legs of a crab.
The Romans called the disease cancer, because of the crab shaped tumors that could be seen under the skin.
However, the origin of the word “cancer” is credited to Hippocrates a great Greek physician (460-370 B.C).
He used the terms karkinos and karkinoma in order to describe tumors.
Karkinos was used for any nonhealing swelling or ulcerous formation, even hemorrhoids, whereas karkinoma was reserved for nonhealing “cancer.”
In English this term translates to carcinos or carcinoma.
Herbalist Galen a prominent Roman physician and philosopher of Greek origin further expended Hippocrates works and studies on cancer.
Together they revolutionized the practice of medicine by removing it from grips of superstitions and magic, to the era of observation and logical reasoning.
Cancer has three meanings: crab, tumor, and the zodiac constellation.
Oldest record of cancer
Cancer is not a new disease.
The world's oldest documented case of cancer comes from ancient Egypt, in 1500 BC.
The details were recorded on a papyrus, documenting 8 cases of tumors occurring on the breast.
And cancer found in the mummified skeletal remains of a female who lived during the Bronze Age (1900-1600 BC).
The tumor in the women skull was of a head and neck cancer.
Another remains of Peruvian Incas, dating back 2400 years ago, contained abnormalities of involvement with malignant melanoma.
Burkitts lymphoma Cancer was also found in fossilized bones remains of a body recovered from ancient Egypt.
The oldest possible hominid malignant tumor discovered in 1932 could either be that of Homo erectus or an Australopithecus.
Type of cancer
There are over 100 types of cancer, affecting various parts of the body.
The most common types of cancer:
• Bladder cancer
• Breast cancer
• Colon cancer
• Endometrial cancer
• Kidney cancer (renal cell)
• Leukemia
• Lung cancer
• Melanoma
• Non-Hodgkin lymphoma
• Pancreatic cancer
• Prostate cancer
• Thyroid cancer
Cancer Classified by Body System
Cancer can affect every organ in the body.
The cells within malignant tumors have the ability to invade neighboring tissues and organs, thus spreading the disease.
There are possibilities for cancerous cells to break free from the tumor and enter the bloodstream and spread the disease to other organs.
This process of spreading is called metastasis.
When cancer metastasized and affected other areas of the body, the disease is still referred to the organ of origination.
For instance, if cervical cancer spreads to the lungs, it is still called cervical cancer, not lung cancer.
These cancers are:
• Blood Cancer
• Bone Cancer
• Brain Cancer
• Breast Cancer Digestive/Gastrointestinal
• Cancers Endocrine Cancers
• Eye Cancer
• Genitourinary Cancers
• Gynecologic Cancers
• Head and Neck
• Respiratory Cancers
• Skin Cancers
What is cancer?
Cancer is a diseases characterized by uncontrollably cell growth.
Cancer harms the body when damaged cells form lumps or masses of tissue called tumors.
Tumors can grow and interfere with the digestive, nervous, and circulatory systems and they can release hormones that alter body function.
Tumors that stay in one spot and demonstrate limited growth are generally considered to be benign.
More dangerous or malignant tumors happen when two things occur:
1. A cancerous cell manages to infect the human body using the blood or lymph systems destroying
healthy tissue in a process called Invasion.
2.This cell manage to divide and grow, making new
blood vessels to feed itself in a process called
Angiogenesis.
Metastasized is a process when a tumor successfully spreads to other parts of the body and grows, invading and destroying other healthy tissues, it is said to have metastasized.
The result of metastasized is a serious condition that is very difficult to treat.
Cancer has claimed the lives of more than 7.6 million people in the world.
