For about six years, I have been teaching some lessons about cancer that are culminating lessons for a unit of study on genetics. Here are some teaching resources that I use:
I show students videos from an NIH CDROM and use the Understanding Cancer student worksheets from the following resource materials that can be ordered from NIH.

Students are assigned nonfiction reading and answer questions that are designed so that students are reading for information. The first article is:

Update: Oprah Winfrey has announced that she is making a film about Henrietta Lacks!
http://www.huffingtonpost.com/entry/hbos-the-immortal-life-of-henrietta-lacks-gets-release-date_us_58a35e8be4b0ab2d2b19b5b2
The HBO presentation of “The Immortal Life of Henrietta Lacks,” based on the book by Rebecca Skloot, is slated to debut Saturday, April 22, at 8 p.m. EST.
I have just watched the HBO presentation "The Immortal Life of Henrietta Lacks," starring Oprah Winfrey. The video may be interesting to those who wish to view a drama about Henrietta Lacks, but the film is not a suitable one for use in the classroom. This is rather disappointing because I was hoping to be able to have an up-to-date, documentary film that could supplement lessons on cancer. The film focuses on the Lacks family and has some mature themes dealing with mental illness, inappropriate language for middle and high school, child abuse and a rape scene. African American studies courses in college could use this video as a supplement. The film is also lengthy and for students, the dialogue might not hold their interest. There is a family featurette at the end of the video. It has some information, but I cannot recommend it as a classroom resource. Mrs. A. 01/13/2018.
I have found some video resources that may be useful. The first four are about the immortal cells of Henrietta Lacks:

The following lesson was used as an assessment/summarizing activity for students, so that they could demonstrate what they had learned about cancer.
Use of Graphic Organizer Introduces Students to New Information in the Subject Area
Purpose Students will practice self-regulated learning by producing a tri-fold brochure that assists them in organizing new information that has been presented. This brochure will be a brochure that can inform and teach others about cancer.
Goals 1. By the end of the lesson, students will be able to find facts and organize reading material.
2. Students will demonstrate the skill of “reading for understanding and organizing information.”
Activity Pass out a sheet of plain, unlined paper (to be used for the brochure) to each student. Instruct and demonstrate to students how to fold the paper into three sections. Indicate where to put the information in the brochure: Front cover to be labeled Understanding Cancer. Inside front cover to be labeled What is Cancer?, in the middle section label should read, Causes of Cancer, inside right, Types of Cancer, and the remaining section, Treatments for Cancer. The back can be used for additional notes. Students can use the information in their binders, as well as the two reading packets: Henrietta’s Dance, and Sticking It to Cancer. Written information, such as facts and vocabulary should be written under each label in the brochure. There should be at least 10 facts for each section. Have the students write down the facts first and then, they may illustrate their brochure with available materials.
Materials Plain unlined paper
Colored pencils, pens.
Grouping Assignment choice: Assigned by teacher – groups of four
Brochure: individual
Discussion: whole class guided by instructor as coach; students may talk quietly while working, but must stick to the topic of their work and not distract others. Monitor their progress.
Reflection: individual
Learning Dependent: structure assignment
Styles Collaborative: students may talk quietly to each other
Independent: activity can be completed on own
Concrete Experience: activity is hands-on and real-life
Reflective Observation: completing tasks give sense of accomplishment
Abstract Conceptualization: activity demonstrates many new possibilities for learning
Active Experimentation: student explore how to efficiently accomplish tasks
Steps Pre-teach activity
Follow-up so that students complete activity
Follow-up Activity prepares students for organizing and learning new information
Evaluation Brochure will be used for study.
