Radiation therapy involves the use of ionizing radiation in an attempt to either cure or improve symptoms. It works by damaging the DNA of cancerous tissue, killing it. To spare normal tissues (such as skin or organs, which radiation must pass through to treat the tumor), shaped radiation beams are aimed from multiple exposure angles to intersect at the tumor, providing a much larger dose there than in the surrounding, healthy tissue. As with chemotherapy, cancers vary in their response to radiation therapy.[151][152][153]
For instance, some people report a sense of calm and peace; others report increased anxiety levels and unpleasant sensations. The intensity of these symptoms will largely depend on an individual’s body composition. In addition, marijuana strains feature different levels of oil concentration that also determines the intensity of the outcomes that a user feels after consumption. Some strains are recommended to produce less profound symptoms and reactions.
Nabiximols (brand name Sativex) is a patented medicine containing CBD and THC in equal proportions. The drug was approved by Health Canada in 2005 for prescription to treat central neuropathic pain in multiple sclerosis, and in 2007 for cancer related pain.[39][40] In New Zealand Sativex® is approved for use as an add-on treatment for symptom improvement in patients with moderate to severe spasticity due to Multiple Sclerosis who have not responded adequately to other anti-spasticity medication and who demonstrate clinically significant improvement in spasticity related symptoms during an initial trial of therapy.[41]
In 2019, the European Commission announced that CBD and other cannabinoids would be classified as "novel foods",[82] meaning that CBD products would require authorization under the EU Novel Food Regulation stating: because "this product was not used as a food or food ingredient before 15 May 1997, before it may be placed on the market in the EU as a food or food ingredient, a safety assessment under the Novel Food Regulation is required."[83] The recommendation – applying to CBD extracts, synthesized CBD, and all CBD products, including CBD oil – was scheduled for a final ruling by the European Commission in March 2019.[82] If approved, manufacturers of CBD products would be required to conduct safety tests and prove safe consumption, indicating that CBD products would not be eligible for legal commerce until at least 2021.[82]

Epigenetic alterations are functionally relevant modifications to the genome that do not change the nucleotide sequence. Examples of such modifications are changes in DNA methylation (hypermethylation and hypomethylation), histone modification[78] and changes in chromosomal architecture (caused by inappropriate expression of proteins such as HMGA2 or HMGA1).[79] Each of these alterations regulates gene expression without altering the underlying DNA sequence. These changes may remain through cell divisions, last for multiple generations and can be considered to be epimutations (equivalent to mutations).


Surgery is the primary method of treatment for most isolated, solid cancers and may play a role in palliation and prolongation of survival. It is typically an important part of definitive diagnosis and staging of tumors, as biopsies are usually required. In localized cancer, surgery typically attempts to remove the entire mass along with, in certain cases, the lymph nodes in the area. For some types of cancer this is sufficient to eliminate the cancer.[146]
The treatment of low blood sugar consists of administering a quickly absorbed glucose source. These include glucose containing drinks, such as orange juice, soft drinks (not sugar-free), or glucose tablets in doses of 15-20 grams at a time (for example, the equivalent of half a glass of juice). Even cake frosting applied inside the cheeks can work in a pinch if patient cooperation is difficult. If the individual becomes unconscious, glucagon can be given by intramuscular injection.
Although many diseases (such as heart failure) may have a worse prognosis than most cases of cancer, cancer is the subject of widespread fear and taboos. The euphemism of "a long illness" to describe cancers leading to death is still commonly used in obituaries, rather than naming the disease explicitly, reflecting an apparent stigma.[190] In Nigeria, one local name for cancer translates into English as "the disease that cannot be cured".[191] This deep belief that cancer is necessarily a difficult and usually deadly disease is reflected in the systems chosen by society to compile cancer statistics: the most common form of cancer—non-melanoma skin cancers, accounting for about one-third of cancer cases worldwide, but very few deaths[192][193]—are excluded from cancer statistics specifically because they are easily treated and almost always cured, often in a single, short, outpatient procedure.[194]
Diabetes can occur temporarily during pregnancy, and reports suggest that it occurs in 2% to 10% of all pregnancies. Significant hormonal changes during pregnancy can lead to blood sugar elevation in genetically predisposed individuals. Blood sugar elevation during pregnancy is called gestational diabetes. Gestational diabetes usually resolves once the baby is born. However, 35% to 60% of women with gestational diabetes will eventually develop type 2 diabetes over the next 10 to 20 years, especially in those who require insulin during pregnancy and those who remain overweight after their delivery. Women with gestational diabetes are usually asked to undergo an oral glucose tolerance test about six weeks after giving birth to determine if their diabetes has persisted beyond the pregnancy, or if any evidence (such as impaired glucose tolerance) is present that may be a clue to a risk for developing diabetes.
The total health care expenditure on cancer in the US was estimated to be $80.2 billion in 2015.[200] Even though cancer-related health care expenditure have increased in absolute terms during recent decades, the share of health expenditure devoted to cancer treatment has remained close to 5% between the 1960s and 2004.[201][202] A similar pattern has been observed in Europe where about 6% of all health care expenditure are spent on cancer treatment.[203] In addition to health care expenditure, cancer causes indirect costs in terms of productivity losses due to lost work days and premature death, as well as informal care. Indirect costs are typically estimated to exceed the health care costs of cancer.[204]

Hash oil is consumed usually by smoking, ingestion, or vaporization.[10] Smoking or vaporizing hash oil is known colloquially as "dabbing",[10] from the English verb to daub (Dutch dabben, French dauber), "to smear with something adhesive".[14] Dabbing devices include special kinds of water pipes ("oil rigs"), and vaporizers similar in design to electronic cigarettes.[10] Oil rigs include a glass water pipe and a hollow tube (called a "nail"), with an indentation on the side which is sometimes covered with a dome.[10] The pipe is often heated with a blowtorch rather than a cigarette lighter.[10]
In addition, other specialists may be involved depending upon where the cancer is located. For example, ob-gyn specialists may be involved with uterine cancer while an immunologist maybe involved in treatment of cancers that occur in the immune system. Your primary care physician and main oncologist will help you to determine what specialists are best to be members of your treatment team.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are medications that are used to reduce pain as well as inflammation in the joints. Examples of NSAIDs include aspirin (Ecotrin), ibuprofen (Motrin), nabumetone (Relafen), meloxicam (Mobic), diclofenac (Voltaren), celecoxib (Celebrex), piroxicam (Feldene), and naproxen (Naprosyn). It is sometimes possible to use NSAIDs temporarily and then discontinue them for periods of time without recurrent symptoms, thereby decreasing the risk of side effects. This is more often possible with osteoarthritis because the symptoms vary in intensity and can be intermittent. The most common side effects of NSAIDs involve gastrointestinal distress, such as stomach upset, cramping diarrhea, ulcers, and even bleeding. The risk of these and other side effects increases in the elderly. Newer NSAIDs called cox-2 inhibitors have been designed that have less toxicity to the stomach and bowels.

Decreased mobility, in combination with the above symptoms, can make it difficult for an individual to remain physically active, contributing to an increased risk of obesity, high cholesterol or vulnerability to heart disease.[24] People with arthritis are also at increased risk of depression, which may be a response to numerous factors, including fear of worsening symptoms.[25]
The three most common childhood cancers are leukemia (34%), brain tumors (23%) and lymphomas (12%).[180] In the United States cancer affects about 1 in 285 children.[181] Rates of childhood cancer increased by 0.6% per year between 1975 and 2002 in the United States[182] and by 1.1% per year between 1978 and 1997 in Europe.[180] Death from childhood cancer decreased by half between 1975 and 2010 in the United States.[181]
