Are tumours unique like people

In summary, tumours are caused by mutations in genes that lead to rapid cell proliferation. This can result in different tumours in the same person, but they can also be similar due to the accumulation of mutations. Tumour cells have the ability to produce their own growth factors, making them autonomous and able to survive in different tissues. While tumours in the heart are rare, they can occur in the myocardium and can be caused by certain types of cancers. Additionally, detachment from the extracellular matrix can lead to a type of programmed cell death called anoikis, which can contribute to the development of cancer.

Are tumours unique like people i.e can two tumours in
one person be different from one another (not just in size).
And is cancer caused by the wrong chemical reactions occurring
in the body, or by the right ones happening too quickly, or
in the wrong order?

Tumours are caused by the rapid proliferation of cells that is not kept in check. This is caused by mutations in genes. Certain mutations will give rise to certain tumours, so tumours in different individuals can be alike. On the other hand, due to the rapid growth of tumour cells more mutations will accumulate causing the tumour cells to change their appearance.

What stops a liver tumour cell from growing in the kidney or thyroid?
And can tumours grow in the heart?
 
  • #4
A cell needs certain growth factors in order to survive in an environment. A normal liver cell would stop proliferating if it ended up in the wrong tissue. A tumour cell has the ability to produce its own growth factors: it has become autonomous and can take care of itself.

I guess tumours can grow in the heart, but it is probably unlikely because it is hard to access and maybe the tissue type (muscle) is not optimal.

Fibrosarcomas and Rhabdomyosarcomas are malignant cancers that develop from connective tissue and muscle respectively, and both can arise from the myocardium. These are extremely rare in the heart, but they can occur nonetheless.

A quote from Michael Onken,Washington university.

Also, there a type of programmed cell death that is mediated by detachment from the extracellular matrix. This is called anoikis and it usually occurs in epithelial cells. If a cell detach but does not die, then i may cause cancer.
 

Related to Are tumours unique like people

1. Are all tumours unique?

Yes, each tumour is unique in its own way. Tumours are caused by genetic mutations and can vary in size, location, and type. These mutations can be influenced by a variety of factors such as genetics, environment, and lifestyle, making each tumour distinct from others.

2. Can tumours be passed down through generations like other genetic traits?

Some tumours, like hereditary cancers, can be inherited from parents. However, not all tumours are inherited. Most tumours are caused by genetic mutations that occur during a person's lifetime rather than being passed down through generations.

3. How are tumours similar to people?

Tumours, like people, are unique and have their own characteristics. They can grow, change, and respond to stimuli. Tumour cells also have mechanisms to protect themselves and can even develop resistance to treatments, similar to how humans can develop immunity to diseases.

4. Can tumours be treated like individuals?

Yes, tumours can be treated as individuals through personalized or targeted therapies. These treatments take into account the unique characteristics of the tumour, such as its genetic makeup, to effectively target and treat the specific tumour.

5. Are there any similarities between different types of tumours?

While each tumour is unique, there are some similarities between different types of tumours. For example, many tumours share common pathways and mechanisms for growth and metastasis. This is why some treatments, such as chemotherapy, can be effective against multiple types of tumours.
