まとめ
携帯電話の使用は,脳がんリスクを増加させるようには見えません. これらの発見を確認するには,特に成長が遅い腫瘍については,さらなる研究が必要である.
科学分野:
- 神経科学は神経科学である.
- エピデミオロジー エピデミオロジー
- 腫瘍学 腫瘍学
背景:
- 携帯電話の使用が健康に及ぼす影響に関するデータは限られている.
- 携帯電話の使用と健康上の結果の間の潜在的な関連を調査することは極めて重要です.
研究 の 目的:
- 手持ちの携帯電話の使用と原発性脳がんのリスクとの関連を調査する.
- 携帯電話の使用が脳腫瘍の危険因子である可能性があるという仮説を検証するために.
主な方法:
- 1994年から1998年にかけて,米国の5つの学術医学センターでケース・コントロール研究が行われました.
- 469人の原発性脳がん患者と422人のマッチングした対照群が,構造化されたアンケートを使用してインタビューされました.
- リスクは,携帯電話の使用時間を毎月数時間,および症例と対照群の間の使用年数を比較することによって評価されました.
主要な成果:
- 手持ち携帯電話の定期的な使用と脳がんのリスクとの間に有意な関連性が見つかりませんでした (OR,0.85;95%CI,0.6-1.2).
- 不定期 (<0.72 h/mo) と頻繁 (>10.1 h/mo) のユーザーには,非ユーザーと比較してリスクが増加しなかった.
- 使用期間と脳がんリスクとの相関は認められませんでした (P =.54).
- わずかな,有意でない傾向は,腫瘍が携帯電話の使用と同じ頭部で発生することを示唆しました (P = .06),しかし,これはすべての腫瘍タイプに一貫していません.
結論:
- 現在のデータは,携帯携帯電話の使用は,原発性脳がんのリスクの増加と関連していないことを示しています.
- より長い追跡期間と腫瘍の潜伏期を考慮することは,包括的な理解のために必要であり,特に成長が遅い腫瘍には必要である.

Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Mutagenicity and Carcinogenicity
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
