CANCER:

Cancer arises because certain cells within a given tissue escape from normal growth controls, replicate more frequently, and migrate to sites distant from the parent tissue where further uncontrolled replication occurs. Such escape is facilitated by the accumulation of mutations within a cancerous cell as a result of the innate and environmental carcinogens to which cellular DNA is subjected. If errors generated in coding DNA are not repaired, these will be transmitted to the daughter strands as the cell divides. Clearly, mutations will arise more rapidly if external mutagenic stimuli are increased, or if the cell is defective in DNA repair systems.

ONCOGENES:

This term refers to a gene which has been mutated to facilitate neoplastic growth. The normal function of such genes may be the synthesis of factors involved in growth control, the cell cycle or apoptosis.

Oncogenes can be broadly divided into two groups, according to whether their oncogenic effect results from overactivity of a ‘proto-oncogene’ or the loss of a ‘tumour suppressor’ function.

Proto-Oncogene:

The majority of known oncogenes are components of signal transduction pathways in which mutations or the presence of increased copies of a gene result in overactivity, mimicking persistent growth factor stimulation. These include genes encoding receptors (e.g. erbB in breast carcinoma), cytoplasmic signalling moieties such as K-ras, and transcription factors such as c-myc (important in gastrointestinal tumours and leukaemias). A recently described class encode mitotic spindle binding proteins; mutation in these genes promote premature exit from anaphase, leading to incorrect chromosome segregation to daughter cells, and anaploidy.

In animals, a number of tumours are caused by retroviruses which carry activated oncogenes, but to date this has not been shown to be a common mechanism in human cancer. Nevertheless, several human cancers are undoubtedly caused by infectious agents. Important examples include human papillomavirus E7 (which inappropriately phosphorylates pRB), leading to cervical carcinoma; herpesvirus 8 (which encodes a cyclin that drives the host cell through the G1-S checkpoint); and Epstein-Barr virus, responsible for Burkitt’s lymphoma and nasopharyngeal carcinoma.

Tumor Suppressor genes tend to encode proteins whose normal function is to inhibit the cell cycle or to induce apoptosis to prevent transmission of uncorrectable DNA defects. Direct inhibitors of the cell cycle include pRB, illustrated in figure 1.15. Other tumor suppressor genes encode components of inhibitory growth factor-signaling pathways, particularly those of transforming growth factor (TGF)-β and its associated cytoplasmic signaling molecules such as Smad2 and Smad4 (which is the DPC4 ‘deleted in pancreatic carcinoma’ gene). As noted in the previous section, neurofibromin encodes as Ras inhibitor which is mutated in neurofibromatosis. APC, the gene mutated in familial adenomatous  polyposis and 60% of sporadic colon  adenomas and carcinomas, is bought to operate as an oncogene by rendering cells less susceptible to apoptosis. P53, a key tumor suppressor gene, normally uses both mechanisms to override other signals which would otherwise stimulate cell proliferation; details of P53 activity are highlighted in figure 1.16. The importance fo P53 is illustrated by the fact that it is inactivated in over 50% of human tumors, including breast and colon carcinomas, and childhood leukaemias.

When an oncogene results from a mutation reducing the activity of a tumor suppressor, a single mutation usually is insufficient to generate oncogenic activity unless an additional mutation in activities the second copy of the gene. This ‘two-hit’ model of tumorigenesis, developed by Knudson, is illustrated in figure 1.17. If, on the other hand, an oncogene results from over activity of a proto-oncogene, a mutation in only one of the two copies may be sufficient to promote tumorigenesis. This is also true in an important exception to the two-hit rule, in the case of the tumor suppressor gene P53, since mutation in only one allele may be sufficient to result in a biological effect. This reflects the operation of the protein as a tetramer, so abnormalities in any one of the subunits may derange its function.

Pass the Bud

Abnormal consuming of alcoholic drinks has demonstrated to improve the threat of cancer. A glass of wine in the finish of the lengthy day just isn’t planning to harm and particular varieties of wine may possibly truly be advantageous for your well being, but a cancer-free way of life should not incorporate all evening drink binges or everyday doses of tequila.

Pale is Stunning

In case you can stand your organic complexion shade, you’ll be able to get yet another action toward stopping cancer. The ultraviolet rays collected within the skin although lying inside the sun or within a tanning bed are among the top will cause of skin cancer.

Serve Up the Veggies

Greens and fruits are really potent in relation to fighting off cancer. These meals are normally full of antioxidants and ton of nutritional vitamins and minerals that your physique requirements to preserve a powerful immune program and stop the formation and development of cancer cells. A lot of vegetables and fruit have elements which are incredibly potent versus cancer.

The much more veggies and fruits it is possible to take in on the every day foundation, the far more safeguarded you are going to be from cancer.

Besides surgery and chemotherapy, radiation therapy is also considered as one of the vital method of cancer treatment. Usually about 50 percent of cancer patient are given radiotherapy at some or the other stage of their treatment. Mostly it is used for the treatment of localized tumors like cancer of brain, skin, and cervix and so on. 
 
Nowadays proton or Cyberknife cancer radiation therapy is gaining popularity, as they are technologically advanced form, causing less harm to normal tissues. These technologies intensely focus on the tumor cells. 
 
Principles of radiation therapy
 
In radiation therapy gi cancer is treated with the help of ionizing radiation. It works by damaging the DNA of tumor cells, stopping their division and growth. Radiation is usually given with an intention to destroy tumor and treating disease. When this radiation is directed towards tumor cells it is not possible to prevent the normal cells surrounding it from damage. The aim of radiation therapy to intensely affect the cancer cells minimizing the exposure to normal cells. 
 
For a solid tumor single therapy cannot provide complement treatment to a patient. Thus radiotherapy is provided with a combination of surgery or chemotherapy, as to make the treatment successful. Even sometimes Cancer Radiation Therapy is given to relieve symptoms like pain or seizures. This procedure is known as palliative treatment.
 
Types of radiation therapy
 
There are several types of radiation therapy available which are provided depending on the cancer. 
 
1.External beam radiation therapy: In this type of therapy radiation beam is created and targeted on the tumor cells. Radiation mainly covers the cancer cells and minimizes the dose to normal cells. It is essential to give radiation in fractions rather going for single dose. This procedure of fractionated exposure gives time to normal cells to repair themselves, protecting them from injury.
2.Proton beam radiation therapy: Nowadays it is the most precise and sophisticated form of external beam therapy available. It is more advantageous to use this therapy over X-rays because of its ability to intensely focus the beams of radiation directly on the tumor cells and minimizing the dose on normal cells. This technique leads to less side effects and increase in survival rates. 
 
3.Intensity modulated radiation therapy: It is also a high power radiation therapy creating a shaped beam, directly delivering high doses of radiation on the affected cells and thus lowering the effect on normal tissues. These days it has been successfully used to treat many types of cancer such as prostate, nasopharyngeal and cervical. 
 
You can find several popular Lung Cancer Treatment involving radiation therapy for treating cancer patients. Along with radiation therapy it is also vital to combine it with other treatments like surgery and chemotherapy as to cure the disease completely. If even a minute cancer cell is left untreated it may lead to occurrence of future cancer.

Cancer is a class of diseases characterized by uncontrolled cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.

Cancer damages the body when damaged cells divide uncontrollably to form tumors or masses called tumors (except in the case of leukemia, where the cancer prohibits normal function of the blood by abnormal cell division in the bloodstream). Tumors can grow and interfere with the digestive, nervous and circulatory systems and can release hormones that alter the function of the body. Tumors that stay in one place and show limited growth are generally considered benign.

Causes of Cancer

1. Cancer is not caused by injury, like a bump or bruise.

2. Cancer is not contagious. Although infection with certain viruses or bacteria may increase the risk of some cancers, can not “catch” cancer from another person.

3.

Having one or more risk factors does not mean you have cancer. Most people who have risk factors never develop cancer.

4. Some people are more sensitive than others to known risk factors.

Symptoms of Cancer

1. Persistent Fatigue: Fatigue is one of the symptoms most commonly experienced cancer. It is usually more common when the cancer is advanced, but still occurs in the early stages of some cancers.

2. Unintentional weight loss: While you may be pleasantly surprised to lose weight without trying, it may be a red flag for many diseases, including cancer.

3. The pain is usually pain an early symptom of cancer, except in some types of cancer that has spread to the bones.

4. Fever: Fever is a nonspecific symptom of many mild to severe conditions, including cancer. With respect to cancer, or a persistent fever is coming and going can often be a sign of stress on the immune system.

Treatment for Cancer

1. If the cancer is confined to one place and has not spread, the most common treatment is surgery to cure cancer. This is often the case with skin cancers and lung cancers, breast and colon.

2. If the tumor has spread to local lymph nodes, these sometimes can be removed.

3. If surgery can not remove all the cancer, treatment options include radiation, chemotherapy or both. Some cancers require a combination of surgery, radiation and chemotherapy.

4. Lymphoma or cancer of the lymph nodes, is rarely treated with surgery. Chemotherapy and radiation therapy is used most often to treat lymphoma.

Home Remedies for Cancer

1. 3-5 chewing Basil (Tulsi) leaves in the morning every day helps prevent cancer type.

2. Drink wheat grass juice in the morning every day is a very useful remedy that reduces the effects of cancer and also prevents cancer.

3. Drinking juice or eating pasta Beal Beal is beneficial in cancer of the blood and bone cancer.

4. Morning drink own urine every day also helps reduce the effects of cancer.
 
5. Drink Cauliflower (Phool Gobi) of juice in the morning helps reduce the impact and prevents cancer.

6. The consumption of carrot juice twice daily on an empty stomach helps to reduce the effects of cancer.

7. Carrot juice mixed with small amount of spinach (Palak) juice taken every day helps reduce the effects of cancer.

8. with cabbage, cauliflower, lemon, carrot, sweet lime (Mosambi), lentils (dal sabutan) with regular meals prevents and reduces the effects of cancer.

9. Drink durva (Dub, an herb used to worship Lord Ganesha) of regular honey juice reduces cancer effcts.

10. Being a good source of antioxidants, tamarind helps fight cancer. Use of tamarind leaves, fruits and bark of various ways to cope with cancer.
 

So you are in search for some alternative therapies for cancer. Is it you who now suffer from cancer? Or is it someone who is so dear to you? Well, whoever it is, it is definitely just so hard for you to deal with cancer now. And you are hoping that these therapies can help you overcome the great challenge.

Most likely, all of the conventional medical treatments have been already tried by you or maybe by someone who is close to you.  And these conventional medical treatments including Chemotherapy, Radiotherapy, surgery, biological therapies, and hormone therapy though have gone through serious testing just did not help at all.  

And now, you want to try these alternative therapies for cancer which have not been through testing, might be not safe and might cause serious side effects but for some might simply just work for cancer sufferers.

Well, some of the alternative cancer therapies that you can try these days include Laetrile, Gerson therapy and shark cartilage.

It is said that Laetrile can improve health, energy levels and well being of someone suffering from cancer. It can detoxify and cleanse the body. However, according to medical experts, Laetrile can cause serious side effects. While Gerson therapy is believed helpful in boosting the immune system and then controlling or curing cancer.  Finally, shark cartilage can also help cancer sufferers as its certain compounds can block the growth of blood vessels which can be helpful in curing cancer. But then, like Laetrile, it can also cause serious side effects.

Alternative therapies for cancer have not been through testing, might be not safe and might cause serious side effects. Of course, you can try these alternative cancer treatments but then you must be very careful. Better consult your doctor first before finally trying out one.

True to most cases the treatment of cancer depends on many factors. Once a lung cancer has been staged, the physician and the patient can discuss with each other now treatment options that will be necessary. The patient should be well informed about the side effects and possible outcomes of a particular procedure.

- Asbestos lung mesothelioma

Everything should be resolved in order to avoid unpleasant. Other factors taken into consideration the general health of patients, medical problems, Treatment (eg chemotherapy) affect, and characteristics of the tumor.

The characteristics of lung tumors helps doctors to separate patients into two groups: those with low risk of cancer recurrence and those with high risk of recurrence of cancer.

Surgical resection is done with the lung cancer patients whose cancer has not spread beyond.

This is done by the following: thoracotomy – opening of the chest for surgical procedures – and medianSternotomy – surgery performed by cutting through the sternum.
- Asbestos lung mesothelioma

Other approaches are limited front thoractomy (ALT) conducted thoractomy head on his chest with a small incision; anterioraxillary thoracotomy (AAT), thoracotomy performed in the chest near the shoulder front and posterolateral thoracotomy (PLT) thoracotomy at the bottom / side torso area. ALT, in particular, is less invasive than standard thoractomy – that is, less interferencethe body through cuts or other drastic measures.

ALT may result in less surgical blood loss, less postoperative drainage, and less postoperative pain of thoracotomy standards.

recently made in other, less invasive procedures for the removal of tumors. For example, the video-assisted thoracoscopy (VAT), or as video-assisted thoracic surgery (VATS) is unknown. This method uses a camera to help introduce and operate on the lung in the chest area. The surgical incisions are made during the sales than for small thoracotomy or sternotomy is required.
