Cancer emerges by DNA mutations. DNA = genes. The mutations lead to protein aberations in the cell. But, some proteins are hormones as well and some of these can cause cancer. To summarize it, let's say that cancer is a disease of genes and DNA in 95% cases and cancer is a disease of hormons in 5% cases. (very roughly, but it is true)
Cancer is a disease that involves mutations in genes, particularly those that control cell growth and division. These mutations can lead to uncontrolled cell growth and the formation of tumors. Hormones can influence cancer development by affecting gene activity, but they are not the primary cause of cancer.
Cancer is primarily a disease of the genes. Specifically, it is a disease characterized by abnormal changes or mutations in the DNA (deoxyribonucleic acid) of cells. These mutations can affect the normal function and regulation of genes, leading to uncontrolled cell growth and the formation of tumors.
Hormones, on the other hand, can play a role in the development and progression of certain types of cancer. Hormone-related cancers, such as Breast cancer and prostate cancer, are influenced by the presence and activity of hormones in the body. In these cases, hormones like estrogen and progesterone in breast cancer or testosterone in prostate cancer can stimulate the growth of cancer cells.
It is important to note that while hormones can contribute to the development of specific types of cancer, the underlying cause of cancer is ultimately genetic mutations within cells. These mutations can be influenced by various factors, including environmental exposures, lifestyle choices, and inherited genetic predispositions.

What Scientist who studies genes?
A scientist who studies genes is called a geneticist. Geneticists study the inheritance of traits, genetic variation, and the role of genes in health and disease. They use various techniques and technologies to analyze DNA and understand how genes function.
How are mutation and cancer related?
Mutations are changes in the DNA sequence of a cell's genes. These changes can occur for various reasons, including exposure to environmental factors, aging, errors during DNA replication, or inherited genetic mutations. When mutations affect genes that regulate cell growth, division, and repair, they can contribute to the development of cancer. Here's how mutations are related to cancer: Uncontrolled Cell Growth: Mutations in certain genes, known as oncogenes, can lead to the activation of proteins that promote cell growth. When these genes are mutated, they may signal cells to continuously divide and grow, contributing to the formation of tumours. Loss of Growth Regulation: Mutations in tumor suppressor genes can result in the loss of normal regulatory functions. Tumor suppressor genes normally inhibit cell division or promote programmed cell death (apoptosis) when necessary. Mutations in these genes can lead to uncontrolled cell growth. DNA Repair Deficiencies: DNA repair genes are responsible for fixing errors or damage in the DNA sequence. Mutations in these genes can result in an accumulation of genetic mistakes, increasing the likelihood of additional mutations and promoting cancer development. Genomic Instability: Mutations can contribute to genomic instability, where the DNA within cells becomes more prone to further mutations. This can create a cascade effect, leading to the accumulation of genetic changes that drive cancer progression. Inherited Mutations: Some individuals inherit specific mutations that predispose them to a higher risk of developing certain types of cancer. While these inherited mutations may not directly cause cancer, they increase susceptibility to the disease. Understanding the genetic basis of cancer has led to advancements in targeted therapies and precision medicine. Identifying specific mutations in cancer cells allows for the development of treatments that target the underlying genetic abnormalities, offering more effective and tailored approaches to cancer therapy. Research in genomics continues to play a crucial role in unraveling the complex relationship between mutations and cancer.
Are DNA or RNA made up of genes?
Genes are segments of DNA that contain the instructions for making proteins. RNA is synthesized from DNA and plays a key role in translating genetic information into proteins. Genes are composed of DNA, not RNA.
How are chromosomes and genes related to each other?
Genes are segments of DNA that are found on chromosomes. Chromosomes are structures made of DNA and proteins that contain genes. Genes carry instructions for making proteins, which determine traits and functions in an organism.
What are made up of genes?
Genes are made up of DNA, which contains the instructions for building and controlling an organism's development and functioning. Genes are segments of DNA that code for specific traits or characteristics. Changes in genes can lead to variations in traits among individuals.
Are genes composed of hormones?
No, genes are not composed of hormones. Genes are segments of DNA that contain the instructions for producing proteins, while hormones are chemical messengers produced by various glands in the body that regulate different physiological processes. While genes can influence the production and regulation of certain hormones, they are not composed of hormones.
How does chemestry affect cancer?
Chemicals that do not cause cancer by themselves but can act with another chemical to cause cancer (cocarcinogens). Damage to DNA in cells can lead to cancer. ... Unrepaired DNA damage can lead to mutations, or changes, in genes, and mutations in certain genes can cause cancer. You can also inherit mutations.
Genetic engineering is used in the biotechnology industry to?

Are genes in DNA or are DNA in geans?
genes are in DNA
What does BRCA mean?
BRCA1 and BRCA2 are two genes in your DNA which when altered or mutated, leads to Breast cancer.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
What do DNA Profiling and Captive Breeding programs to help Tasmanian Devils?
DNA profiling can help determine the particular genes which are active in the deadly cancer cells. This inturn can help scientist find a cure for the disease. Captive breeding ensure that there are a population of healthy devils which can be sustainably released into the wild.
How much of your DNA contains genes?
20.3% of your DNA contains genes
What do genes have the instructions for?
Genes, or DNA, have the blueprints for producing proteins. The proteins produced by DNA not only are the building blocks for the whole body, but they are used to trigger every other reaction in the body. For example, DNA can create proteins such as enzymes, which assist chemical reactions, hormones, which signal other cells to do certain functions, etc.
Scientists are trying to find a way to turn off the genes that cause genetic disease This would be a type of?
DNA Manipulation
Do all the nucleotides in human DNA belong to genes?
No - genes are the parts of DNA that code for a functional product (such as a protein). There are other parts of the DNA which are not genes.
Cancer can be caused by changes in this?
Cancer can be caused by changes in the DNA of cells. The development of cancer is often associated with genetic mutations or alterations in the DNA sequence of certain genes. These changes can disrupt the normal regulatory mechanisms that control cell growth, division, and death. The key factors related to cancer development include: Genetic Mutations: Mutations in specific genes can lead to uncontrolled cell growth and the formation of tumors. Mutations can be inherited (germline mutations) or acquired during a person's lifetime (somatic mutations). Oncogenes: Oncogenes are normal genes that, when mutated or activated, can promote the development of cancer. These genes are involved in regulating cell growth and division. Tumor Suppressor Genes: Tumor suppressor genes normally prevent the uncontrolled growth of cells. Mutations that inactivate these genes can contribute to cancer by allowing cells to evade normal growth controls. DNA Repair Genes: DNA repair genes are responsible for fixing errors or damage in the DNA sequence. Mutations in these genes can lead to the accumulation of genetic abnormalities and an increased risk of cancer. Epigenetic Changes: Epigenetic modifications, such as alterations in DNA methylation or histone modifications, can influence gene expression without changing the underlying DNA sequence. Abnormal epigenetic changes can contribute to cancer development. Environmental Factors: Exposure to certain environmental factors, such as tobacco smoke, ultraviolet (UV) radiation, certain chemicals, and infectious agents, can cause DNA damage and increase the risk of cancer. Lifestyle Factors: Unhealthy lifestyle choices, including poor diet, lack of physical activity, and excessive alcohol consumption, can contribute to DNA damage and increase susceptibility to cancer. Heredity: Inherited genetic mutations passed down from one generation to the next can increase the risk of certain cancers. However, most cancers are not directly inherited but result from a combination of genetic and environmental factors. Understanding the genetic and molecular changes associated with cancer is crucial for developing targeted therapies and personalized treatment approaches. Early detection and intervention are also essential for improving outcomes in cancer patients.
