Why can metastasizing cancer cells get into the lymphaticsystem more easily than they can enter the bloodstream?

In a patient of 60 years old after the surgical removal of stomach cancer and subsequent treatment, an enlarged lymph node in the left supraclavicular area was detected. Atypical cells, which were similar to the cells of a previously removed tumor, were found after the biopsy of this lymph node, Questions: 4) What is the name of tumor cells spreading throughout the body? 5) What is the difference between tumor cells and normal cells?

Jordan has an enlarged lymph node along the side of his neck,and he is worried that the structure may be a lymphoma. Whatare some criteria to help distinguish between infected lymphnodes and malignant lymph nodes?

1. Mark Thompson is a 16-year-old patient who was admitted yesterday to the pediatric oncology unit for newly-diagnosed Hodgkin lymphoma. Further testing revealed that Mark has involvement of lymph nodes on both sides of his diaphragm and in his spleen. He is scheduled to begin chemotherapy this evening. Mark states, “I can’t believe this is happening. It feels like my whole life changed overnight. I hate not knowing what will happen.”  What stage of lymphoma does Mark have? What clinical manifestations would you expect to see in your assessment? What are some oncological emergencies that can occur during chemotherapy treatments? What impact does a cancer diagnosis have on the psychosocial status of the patient and their family? What referrals can the nurse make to minimize this impact?

You are an oncologist at a local medical center and you have 3 patients with various types of lung cancer. You evaluate the cell surface markers of the cancer cells from each patient using a technique called immunohistochemistry. Which of the following patients is most likely to respond to immunotherapy (i.e. the immunotherapy is likely to work to target cancer cells)? Patient 1: PDL-1 is 0% Patient 2: PDL-1 is 10% Patient 3: PDL-1 is 20%

FIGURE 11.1L2 Lymphoid organs: (A) overview of the lymphatic organs and vessels 10 Which of the following is not a function of the lymphatic system? a. Maintaining blood pressure b. Absorbing dietary fats c. Activating the immune system d. Transporting excess interstitial fluid back to the heart

A bacterial cell has been tagged by antibodies and is destined to undergo phagocytosis. Discuss the process of phagocytosis and the steps involved. Make sure to discuss in your answer lysosomes, digestion and phagolysosomes.

Among the pointed parts, which structure will the proliferation of lymphocytes occur while substances are removed by phagocytosis?  Structure labelled A     Structure labelled D     Structure labelled E     Structure labelled C

Metastasis is the spread of cancer to new tissue/regions within the body. Using breast cancer as an example, explain how the lymph system could facilitate metastasis.

What do you mean by ‘lymph’. Mention its function.

In the disease mononucleosis (“mono”), the spleen enlarges because of increased numbers of phagocytes and other cells. Common signs and symptoms of this disease include pale complexion, a tired feeling, and a lack of energy sometimes to the point of not being able to get out of bed. What might cause these signs and symptoms?   (Please include your citation, if there is. Thanks!)

Justine, a 39-year-old female, has recently been diagnosed with lymphoma. She has a family history of several cancers but not lymphoma. Her personal medical history includes mononucleosis, asthma, and two full-term pregnancies and vaginal births. Before her diagnosis, she had been feeling “generally sick” and felt several lumps on her neck and armpits. She had a fever that wouldn’t go away and had been waking up sweaty in the middle of the night. Microscopy showed the presence of Reed-Sternberg cells. Which of the following is true of Justine’s diagnosis?   It is caused by a genetic mutation of a lymphocyte.   It is easily treatable and she has a great prognosis.   It causes her lymphocytes to shrink.   It causes her body to launch an autoimmune attack against its own lymphocytes.

A person with lymphoma receives a dose of 35 gray in the form of gamma radiation during a course of radiotherapy. Most of this dose is absorbed in 18 grams of cancerous lymphatic tissue. i. How much energy is absorbed by the cancerous tissue? If this treatment consists of five 15-minute sessions per week over the course of 5 weeks and just one percent of the gamma photons in the gamma ray beam are absorbed, what is the power of the gamma ray beam? ii. iii. If the gamma ray beam consists of just 0.5 percent of the photons emitted by the gamma source, each of which has an energy of 0.03 MeV, what is the activity, in Curies, of the gamma ray source?

Based on what you know about how lymphatic vessels are located and how they function, think of two (2) reasons that there might be such a high concentration of lymphatic vessels in the breasts of adult females? Please answer this knowledge and not from the internet. It will be really appreciated. Thank you

After his surgery, Nilesh developed fever, Prior to surgery, he was undergoing chemotherapy with drugs that are known to kill healthy bone marrow cells as well as cancerous cells. Considering this, why do you think Nilesh'fever is of particular concern to his medical team

What is the physical occurrence that makes lymph nodes swell?    1. Your nervous system notices an infection and facilitates the relaxation of smooth muscle around lymph nodes, which allows them to get bigger    2. There are increased numbers of memory B cells, plasma cells, and cytotoxic T cells in the lymph node    3. Epithelial cells that line the lymph node replicate and add more layers of cells to the lymph node   4. There are large amounts of histamines present in the lymph nodes, which causes blood vessels inside the nodes to vasodilate

Why are the axillary lymph nodes often biopsied in cases of suspected breast cancer?
