A: Some types of cancer (including melanoma and cancers of the breast, ovary, prostate, and colon) tend to occur more often in some families than in the rest of the population. It is often unclear whether a pattern of cancer in a family is primarily due to heredity (due to gene mutations), factors in the family environment or lifestyle, or just a matter of chance. Most cancer causing gene changes are the result of factors in lifestyle and environment.

Yes, some types of anemia are due to inherited or genetic defects. Sickle cell anemia occurs most frequently in people of African, African-American, and Mediterranean descent. Thalassemia (or Cooley's anemia) is found in people of Mediterranean and Southeast Asian descent. These types of anemia are extremely common. Another inherited anemia is Fanconi anemia, but this is very rare.

No, cancer is generally not inherited. There has been no evidence of cancer being inherited till date. However, there are cases of many cancer patients within a family or over generations. Since cancer is a disease related to genetics, certain genetic predisposition can be carried forward from generation to generation in the family, if there is a history of cancer in a family, prudence demands that the family should get themselves checked and exercise all necessary restraints.

On average, by the age of 70, women with one of the alterations tested for in this study have about a 50 percent chance of being diagnosed with breast cancer and 16 percent chance of developing ovarian cancer. Men with an alteration have about a 16 percent chance of developing prostate cancer by the age of 70. However, for any individual with an alteration, a precise estimate of risk is not possible.

There are different kinds of eye cancers. Below are some of the places near or on the eye where cancers can grow and the types that may be present on each one of these places: Eyelid tumors. Basal cell carcinoma is the most common type of eyelid cancer. It can be removed with surgery. Other types of eyelid tumors include squamous cell carcinoma, sebaceous cell carcinoma, and malignant melanoma. Tumors that grow on the surface of the eye (conjunctival tumors).

There are many different kinds of cancer depending on where in the body the cancer starts and the type of cell involved. The most common types are prostate, breast, lung, and colorectal cancers. Out of every twenty cancer diagnoses, about three will be breast cancers, three will be prostate cancers, three will be lung cancers, and two will be colorectal. There will be about one in the bladder or kidney, one in the ovary, uterus or cervix, and one will be a lymphoma.

Most cases of this cancer are "random." That means they are not inherited. But a person who has a parent, sibling, or child who has had this cancer is at higher risk. That risk is even higher if the cancer happened at a young age. Some conditions that can be passed on in families may also increase the risk. An example is inflammatory bowel disease.

Cancer cannot be inherited i.e. cannot it be passed from one generation to another. Willis the famous bio-pathologist had generalized that most of the 'cancer families' exemplify only the laws of chance (Pathology of Tumors, Butterworths, London, 1967). Scheinfeld commented way back in 1939 on the problem - 'Thus, in grandmother, mother and daughter, where all have breast cancers, each of their cancers may be entirely unrelated to the others ..

It is relatively rare for people to have an inherited susceptibility to cancer. Most people that develop cancer will not have the inherited form but instead will have developed a sporadic cancer. If there is a strong family history of a specific cancer or if you are concerned, you may wish to talk to your GP who will be able to advise you and if necessary refer you to a clinical genetics service.

You can talk to your GP or practice nurse. Alternatively you may wish to look at the following websites:

Genetics may play a role in PMDD. Studies have shown that identical twins are more likely to share the disorder (93%) than non-identical (fraternal) twins (44%), and daughters of mothers with PMDD are more likely to have it themselves. However, no specific genes have been identified to account for PMDD. It is best to simply say that genetics may put a woman at greater risk for developing the disorder.

There is a genetic factor in the development of allergic disease. If one parent has allergic disease, the estimated risk of a child to develop allergies is 48%; the child's estimated risk grows to 70% if both parents have a history of allergies.

Research shows that the risk for developing alcoholism does indeed run in families. The genes a person inherits partially explain this pattern, but lifestyle is also a factor. Currently, researchers are working to discover the actual genes that put people at risk for alcoholism. Your friends, the amount of stress in your life, and how readily available alcohol is also are factors that may increase your risk for alcoholism. But remember: Risk is not destiny.

Research shows that ADHD tends to run in families, so there are likely to be genetic influences. Children who have ADHD usually have at least one close relative who also has ADHD. And at least one–third of all fathers who had ADHD in their youth have children with ADHD. Even more convincing of a possible genetic link is that when one twin of an identical twin pair has the disorder, the other is likely to have it too.

In humans, there are two modes of inheritance: autosomal dominant and autosomal recessive (with at least two, and possibly three different autosomal dominant forms of PKD caused by different genes at different loci). To date, only the autosomal dominant form has been identified in cats. To quote Dr. DiBartola, Professor of Veterinary Clinical Sciences at The Ohio State University College of Veterinary Medicine, and Co-Editor of the Journal of Veterinary Internal Medicine (one of the Dr.

Genetics is a complex subject, and The Foundation Fighting Blindness has prepared another booklet, "The Inheritance of Retinal Degenerations," to explain this topic in detail. (This can be ordered by using The Foundation's Publication Order Form.) There are so many different forms of RP, which fall within one of three standard inheritance patterns. Each type of inheritance will create a different pattern of affected and unaffected family members.

Most cases of PWS are attributed to a spontaneous genetic error that occurs at or near the time of conception for unknown reasons. In a very small percentage of cases (2 percent or less), a genetic mutation that does not affect the parent is passed on to the child, and in these families more than one child may be affected. A PWS-like disorder can also be acquired after birth if the hypothalamic portion of the brain is damaged through injury or surgery.

Most cases of epilepsy are not inherited, although some types have a genetic basis. Most of these types are easily controlled with medication. Epilepsy syndromes with a genetic basis: Primary Generalized Epilepsies, Benign Rolandic Epilepsy, Nocturnal Frontal Lobe Epilepsy, Familial Temporal Lobe Epilepsy, Benign Familial Neonatal Seizures and Benign Familial Infantile Spasms.

Only 3 to 5% of cases are inherited; the rest arise as an accident of chromosome arrangement during meiosis. For details, see my essay on the origin of trisomy 21 or Dr. Paul Benke's essay on the types of DS, and the risk and recurrence risk of DS. No. Down syndrome occurs at conception, so nothing in the pregnancy can cause Down syndrome to occur. As for prior to conception, the research all shows that drug or alcohol use does not increase the risk of having a child with DS.

Cervical cancer "in situ", is not required to be reported to the Registry, and are not included in the statistics. Certain skin cancers are not reportable unless they are diagnosed at an advanced stage.

There are hundreds of different types of cancer. They are identified by the type of body tissue involved or by the body part involved. The major classifications of cancer are: Carcinoma: a malignant tumor found in the outermost covering or lining of body surfaces or organs. These tumors are found on the skin, in the mouth and throat, stomach and bowel, or in organs like the mammary gland, liver, lung or bladder.

TThe most common kinds of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma arises from the basal cells, small round cells found in the lower part (or base) of the epidermis. SSquamous cell carcinoma begins in squamous cells, which are thin, flat cells that look like fish scales found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the passages of the respiratory and digestive tracts.

Yes. Orthodox or "conventional" therapies are well covered in the medical literature so the results of chemotherapy, radiation therapy, hormone therapy, and surgery are well represented. In addition, the newer modalities such as biological therapy, immunotherapy and gene therapy are also covered. Alternative therapies are also reported, but less frequently because so few of them are actually tested.

Currently, research is being done to determine the effectiveness of cryotherapy for tumors of the brain, kidney, bone, lung, and spine. In addition, researchers are evaluating its usefulness in freezing and shrinking benign breast lumps.

BMT and PBSCT are most commonly used in the treatment of leukemia and lymphoma. They are also used in the treatment of childhood brain tumors and neuroblastoma (an uncommon cancer that occurs most often in children). Researchers are evaluating BMT and PBSCT in clinical trials (research studies) for the treatment of various types of cancer, including cancers of the breast and ovary; multiple myeloma; and Wilms' tumor (a type of kidney cancer that occurs in young children).

The Issels treatment has been effectively administered with all types of cancer, as it is not only focused on the cancer cells and tumors, but on the internal bodily environment on which the cancer cells grow. Research has shown that a cancer cell cannot thrive and replicate, if it does not find the necessary preconditions, if the surrounding tissues do not allow it.
