Hepatocellular carcinoma

Hepatocellular carcinoma is the major histologic type of malignant primary liver neoplasm. It is the fifth most common cancer and the third most common cause of death from cancer worldwide. The major risk factors for HCC are chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, prolonged dietary aflatoxin exposure, alcoholic cirrhosis, and cirrhosis due to other causes. Hepatoblastomas comprise 1 to 2% of all malignant neoplasms of childhood, most often occurring in children under 3 years of age. Hepatoblastomas are thought to be derived from undifferentiated hepatocytes (Taniguchi et al., 2002). [from OMIM]

Stress

Everyone feels stressed from time to time. Not all stress is bad. All animals have a stress response, and it can be life-saving. But chronic stress can cause both physical and mental harm. There are at least three different types of stress:: -Routine stress related to the pressures of work, family, and other daily responsibilities. -Stress brought about by a sudden negative change, such as losing a job, divorce, or illness. -Traumatic stress, which happens when you are in danger of being seriously hurt or killed. Examples include a major accident, war, assault, or a natural disaster. This type of stress can cause post-traumatic stress disorder (PTSD). Different people may feel stress in different ways. Some people experience digestive symptoms. Others may have headaches, sleeplessness, depressed mood, anger, and irritability. People under chronic stress get more frequent and severe viral infections, such as the flu or common cold. Vaccines, such as the flu shot, are less effective for them. Some people cope with stress more effectively than others. It's important to know your limits when it comes to stress, so you can avoid more serious health effects.

DNA damage

Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS. [from MeSH]

cytotoxicity

The adverse effect of some iatrogenic therapies. It is an accepted side effect in radiation therapy where the desired effect is to kill rapidly growing tumor cells. In the killing of tumor cells, other cells that are rapidly growing e.g hair, mucous membranes are also killed. [from NCI]

Antioxidants

Antioxidants are substances that may protect your cells against the effects of free radicals. Free radicals are molecules produced when your body breaks down food, or by environmental exposures like tobacco smoke and radiation. Free radicals can damage cells, and may play a role in heart disease, cancer and other diseases. . Antioxidant substances include : - Beta-carotene . - Lutein . - Lycopene. - Selenium. - Vitamin A. - Vitamin C. - Vitamin E. Antioxidants are found in many foods. These include fruits and vegetables, nuts, grains, and some meats, poultry and fish. .  [from MedlinePlus]
