Carcinomas of the breast are malignant tumours, usually adenocarcinomas arising from the epithelial cells of the lactiferous ducts in mammary gland lobules. Metastatic cancer cells that enter a lymphatic vessel usually pass through two or three groups of lymph nodes before entering the venous system. Breast cancer typically spreads by means of lymphatic vessels (lymphogenic metastasis), which carry cells from the breast to the lymph nodes, chiefly those in the axilla. The cells lodge in the nodes, producing nests of tumor cells (metastases). Abundant communications among lymphatic pathways and among axillary, cervical, and parasternal nodes may also cause metastases from the breast to develop in the supraclavicular lymph nodes, the opposite of breast, or the abdomen.

When cancer cells invade other cells and tissues in the body the cancer is said to have done what?
When cancer cells invade other cells and tissues in the body, the cancer is said to have metastasized. This means that the cancer has spread from its original location to other parts of the body through the bloodstream or lymphatic system. Metastasis is a key factor in determining the stage and prognosis of the cancer.
What property of cancer cells allows them to spread throughout the body?
Cancer cells can spread throughout the body by a process called metastasis, where they can invade nearby tissues and travel through the bloodstream or lymphatic system to form new tumors in other parts of the body. They acquire the ability to metastasize due to genetic mutations and changes in cell behavior that allow them to detach from the original tumor and survive in different environments.
What is the difference between invasion of cancer cells and metastasis of cancer cells?
Invasion of cancer cells refers to the ability of cancer cells to penetrate and spread into nearby tissues. Metastasis, on the other hand, involves the spread of cancer cells from the primary tumor to distant organs or tissues in the body through the bloodstream or lymphatic system. Metastasis is a more advanced stage of cancer progression and is often associated with a poorer prognosis.
Where are cancer cells found in the body?
Cancer cells are found in the affected organ or tissue. There are several types of cancer depending on anatomical location within the body like skin cancer, blood cancer, lung cancer etc. Also it depends on how a particular type of cancer spreads like the Carcinomas spread through lymph so the cancer cells can be found at lymph nodes whereas, the sarcomas spread through blood. Another noteworthy thing is that in the later stages of cancer it can spread to a distant organ and start a secondary cancer in the new location.
How do cancer cell form tumor in other tissues?
Cancer cells can form tumors in other tissues through a process called metastasis, where they break away from the primary tumor, travel through the bloodstream or lymphatic system, and invade other organs or tissues in the body. They can then proliferate and grow in these new locations, forming secondary tumors.
Where did Jacquie Onassis cancer spread to?
She had Lymphoma an allied disease of the cancer type- that spread through her lymphatic ducts- may have impaired breathing and conversation.
How do cancer tumors spread?
Cancer tumors can spread through a process called metastasis, where cancer cells break away from the original tumor and travel through the bloodstream or lymphatic system to form new tumors in other parts of the body. This can make the cancer more difficult to treat and control.
How does cancer spread in the body?
Cancer can spread in the body through a process called metastasis, where cancer cells break away from the original tumor, travel through the bloodstream or lymphatic system, and form new tumors in other parts of the body. Metastatic cancer is more difficult to treat and is often associated with a poorer prognosis.
What is significant about the lymphatic system with the regard to the spread of cancer?
it does it
How does lymphatic spread take place in krukenberg tumor?
Lymphatic spread in Krukenberg tumor is believed to occur through direct invasion of lymphatic vessels by cancer cells in the ovaries and subsequent spread to regional lymph nodes. The tumor cells may enter the lymphatic vessels in the stroma of the ovary and metastasize to lymph nodes in the pelvic and abdominal regions. This mode of spread can lead to further dissemination of cancer cells to distant sites in the body.
What are the types of metastasis?
Metastasis can be classified into three main types: hematogenous, where cancer cells spread through the bloodstream to distant organs; lymphatic, where cancer spreads through the lymphatic system to nearby lymph nodes; and transcoelomic, which involves the spread of cancer cells across body cavities, such as the peritoneum. Each type reflects different pathways and mechanisms by which cancer can disseminate from its original site.
How can the lymphatic circulation become clogged?
The lymphatic circulation may become clogged by infection, injury, or several other types of cancer that have spread through lymphatic channels. Swelling, sometimes massive, can result from blocked lymphatics.
How can thyroid cancer spread in other body part?
Thyroid cancer can spread to other parts of the body through a process called metastasis. Cancer cells can break away from the original tumor in the thyroid and travel through the bloodstream or lymphatic system to distant organs, such as the lungs, bones, or liver. Once they reach these areas, the cancer cells can grow and form new tumors. The likelihood and pattern of spread depend on the type and stage of the thyroid cancer.
explain the role of the lymph node in the spread of cancer?
When a person has cancer, sometimes the cancer will metastize to other areas of the body. When cancer has metastizes, the lymph nodes can become involved due to the cancer spreading through the lymphatic fluid.
Does the lymphatic system play a role in the spread of pathogens and cancer cells?
yes
Is cancer spread through the body through a process called melanoma?
No , its actually called metastasis.
How does cancer spread from the lymphatic system?
Cancerous cells can also invade other organs through the circulatory system of the lymph, causing those organs to malfunction.
